EXTORTION
On November 24, 1971, an unknown man using the name Dan Cooper, boarded Northwest Airlines Flight #305, at Portland International Airport, Portland, Oregon, en- route Seattle, Washington.
As the plane was taxiing down the runway,
Stewardess occupied the seat reserved for the stewardesses on the right side of the plane and behind the last row of passenger seats. The unknown subject, who occupied the center seat in the last row of three seats, turned and handed her an envelope which she did not open for a few minutes until he glanced at her several times. She then opened the envelope and read the enclosed note which said: "Miss - I have a bomb here and I would like you to sit by me." At this point Stewardess came toward the rear of the plane and handed the note.

b6 b7C
on the flight, later advised that according to notes he made during the incident, the emergency signal from Stewardess was received on the intercom at 3:59 PM.
Stewardess then sat next to the hijacker who opened a black attache case and showed her what he said was a bomb. She described the contents of the attache case as a bundle of red sticks, which she believed was dynamite. The bundle consisted of six or eight red colored sticks approximately six to eight inches long with no writing on the outside. The hijacker was holding in his hand a wire which led to the bundle of sticks and indicated that he could detonate the bomb by touching the wire to a contact. Also in the attache case was a cylindrical shaped battery about eight inches long.

that Portland had set out a lot of unnecessary investigation since the purpose of the thing was simply to get a photo of the suspect and have it shown to witnesses rather than getting all the background.
3. He wanted to know if we had considered having a Northwest plane fly Agents over the exact course at night so that we could look down and see just what the situation was when the "bump" occurred at 8:10 or 8:12 PM. I told him we had considered this and also had considered hiring someone to parachute from the plane but the problem was that there was no way of duplicating the conditions which existed at the time. He requested we put some type of language in a teletype about this.

On 7/19/79, advised that the probability that this decal came from the same aircraft hijacked by COOPER is about ninety-nine per cent. He noted that there is a slight difference in the color of the lettering of the decals placed on the aircraft and that recovered. This, of course, could be accounted for by the weather conditions. The second thing noted by is that the decal does not appear to be as worn as one would think after having been located in the out state area for the past eight years. He thought that a decal in this condition would have been handled by preditors more than it appears. suggested that perhaps the Bureau could contact the manufacturer of the decal in order to determine if the decal could withstand the weathering conditions and still be in this condition.

An FBI agent here said this morning that the piece of plastic decal found by a Kelso hunter last November could have dropped from any Boeing 727, not necessarily the one hijacker D.B. Cooper bailed out of Thanksgiving eve 1971.
John Gordon, of the bureau's Vancouver office said. "There is no positive proof that the decal came from the Cooper plane."
An FBI spokesman in Seattle. speculated Thursday that the decal may have fallen off the Cooper plane when the craft was used for a re- enactment of the hijacking six weeks after it occurred.
"We noticed the decal was missing after that, but not before," the spokesman said.
A spokesman added that the placards, used to give emergency directions for the rear door on 727s. have been known to fall off under normal conditions.
Earlier this week Cowlitz County
Sheriff Les Nelson disclosed the discovery of the decal last November by Carroll Hicks, a self-employed welder from Kelso who was elk hunting when he found the bit
Earlier this week Cowlitz County
Sheriff Les Nelson disclosed the discovery of the decal last November by Carroll Hicks, a self-employed welder from Kelso who was elk hunting when he found the bit of debris.
"It's one in a million that any other plane could have lost it in the area in which D.B. Cooper jumped," Nelson said.
But while the 10-inch square decal has stirred wide interest. Gordon expressed doubt it would help solve the mystery behind the case.
"It's interesting, but I don't think it will help us find Cooper," he said of the decal.
Gordon said the FBI has no plans to resume the search for Cooper and the $200.000 that left the airplane with him.
Cowlitz County ' officials have indicated they do not plan to search for. Cooper, either. but they did say they hope to encourage people to "keep their eyes open," when thes: are in the area the decal was found, about 12 miles east of Kelso.

He heard on the news that a plastic decal, possibly from D. B. COOPER's plane, was found in the Castle Rock, Washington, area recently. He recalled that in October, 1978, he was hunting in that general area and saw in a tall tree something flapping. The area he was in was north of Toutle Park. This item he saw in the tree was light in color and he feels, perhaps, that might have been a parachute, possibly the one used by COOPER. He did indicate, however, this thing he saw could have been a weather parachute and could have been there in his previous trips to that area, although he has not seen it before. He does not know if this information will be of any assistance to the FBI, but in the event the FBI desires to find the exact location of this item, he and his cousin are willing to escort the FBI into the area and point out the article, if they can find it, to the FBI.

Northwest Orient Airlines, Minneapolis- St. Paul International Airport, advised as follows:
After having been displayed the decal of Boeing Aircraft Company noting the emergency exit handle on the aft airstair, advised that the decal probably came off when the stairs were lowered due to the change in air pressure. He recalled that about two days after the hijacking by D. B. COOPER, he and. took the same aircraft used by COOPER in order to determine whether or not there was a change in pressure at the time he parachuted from the aircraft. recalls that he and flew out over the ocean and ran their

the Castle Rock, Washington, is rather close to the path taken by COOPER. He added that if indeed the decal came from the same aircraft used by COOPER, it would have floated about in the air currents much like a leaf and could have found its way near Castle Rock.

1SUMMARY
This report presents the results of tests conducted on the Model 727 airplane to evaluate the characteristics of the aft airstair when extended inflight and the associated effects on airplane performance and handling. The airstair was extended both by allowing it to free- fall and by utilizing normal hydraulic power. These extensions were made with the airplane trimmed for level flight at 125 knots and flaps at 25 degrees. The airstair extended a nominal 8.5 degrees when allowed to free-fall and it required only approximately one-tenth unit of nose-down trim to compensate for the stair. The stair extended a nominal 13.5 degrees with hydraulic power and this caused approxi- mately a three-tenths unit nose-down trim change. The airplane was also accelerated to Vyo with flaps up and the airstair free-floating. The airstair was quite stable when it was down and no airplane control problems were experienced. No excessive cabin pressure transients were noted with the aft entry door open and the stair extended. The environment near the aft entry door allowed it to be safely opened and the stair retracted at speeds up to 300 knots.
The environment near the aft entry door allowed it to be safely opened and the stair retracted at speeds up to 300 knots. At 300 knots, it was also found that the airstair would not free-fall when unlatched.

6-7000INTRODUCTION
Reference (a) specified that the aft airstairs should be released in flight and allowed to free-fall without utilizing hydraulic power, simulating an in-flight failure of the airstair up-latch. In addition, it also specified that the airstair should be extended by utilizing normal hydraulic power. The aerodynamic characteristics of the extended airstair and the associated. effects on airplane performance and handling were also to be evaluated at speeds up to Vio-
The initial evaluation was conducted on Test 100-1, with most of the produc- tion airstair cavity panels removed. They were removed to avoid the possi- bility of panel failure causing damage to wiring and tubing in the area, in the event large
They were removed to avoid the possi- bility of panel failure causing damage to wiring and tubing in the area, in the event large pressure differentials should occur. Testing was done with flaps at 25 degrees and a nominal airspeed of 125 knots, with the airstair allowed to free-fall and also extended with hydraulic power. In addition, with the aft airstair free-floating, the flaps were retracted and the air- plane was accelerated to Vio. The testing was repeated on Test 100-3 with all the production airstair cavity panels installed, with the exception that no hydraulic airstair extension was attempted. In addition, two un- successful attempts were made to release the airstair and allow it to free- fall at an approximate airspeed of 300 knots.
Both tests were conducted from Boeing Field, Seattle, on Airplane N72700. Boeing pilots, (r. J. Waddell and Mr. S. L. Wallick, conducted Test 100-1, with Boeing Test Engineer, Or. R. F. Brown, operating the aft airstair. Test 100-3 was conducted by Boeing pilots, Mr.
Wallick, conducted Test 100-1, with Boeing Test Engineer, Or. R. F. Brown, operating the aft airstair. Test 100-3 was conducted by Boeing pilots, Mr. J. Waddell and with Boeing Test Engineer, Mr. C. M. Clark, operating the airstair. DECEASED
CONFIGURATION
Model 727-22, Airplane N72700, was in production configuration as detailed in Reference (b) except for the removal of the production airstair cavity panels during Test 100-1 and the removal of the airstair spring-loaded latch stop during both tests. In addition, FC 751-1-1 was incorporated on the airplane for both tests. This FC provided a cable to restrain the airstair to a maximum extension of 25 degrees and thus prevent airstair damage during landing in the event the stair could not be retracted in flight.
The airplane cabin was depressurized during both tests, with the ram air valve closed, both air conditioning packs off, and the manual pressure con- troller in full decrease pressure.
INSTRUMENTATION AND DATA REDUCTION
A Pulse Duration Modulation (PDM) magnetic tape system and a photorecorder were used to record performance and calibrated data.
INSTRUMENTATION AND DATA REDUCTION
A Pulse Duration Modulation (PDM) magnetic tape system and a photorecorder were used to record performance and calibrated data. Airspeed and altitude were measured using the pilots' production pitot-static system. The aft airstair was instrumented to measure position in degrees from the up and locked position. The static pressure in Section 48 was measured by a pick-up that was located on the LH side of the airplane, outboard of the LH cavity side panels. Airplane cabin pressure and rate of climb were recorded on the

(Pages /3 through 23).
RESULTS AND DISCUSSION
The aft airstair control system was in production configuration for both Test 100-1 and 100-3, except for removal of the spring-loaded latch stop. The latch stop was removed to permit moving the control handle to the UP position with the airstair down, thus simulating a condition which could exist if the up-latch failed inflight. With the airstair down and the control handle in the UP position, both the UP and DOWN side of the stair actuator are connected to the system return line through the control valve, allowing the airstair to free-float. The control handle was in the UP position during all test conditions, except for stair extension and retraction and the stair extension utilizing hydraulic power.
The control handle was in the UP position during all test conditions, except for stair extension and retraction and the stair extension utilizing hydraulic power.

The sequence during Test 100-1 (Reference (d)) started with the airplane trimmed for level flight at 10,000 feet altitude and 125 knots airspeed, flaps at 25 degrees, cabin depressurized, and the airstair up and locked. With the operator wearing a parachute and secured by a restraining strap, the aft entry door was opened. No difficulty was experienced in opening the aft entry door and the operator then moved the upper control handle to the DOWN position without depressing the handle trigger. Thus, the air- stair was unlocked and allowed to free-fall. After the stair started to extend, the control handle was moved to the UP position and the stair was allowed to free-float. No noticeable out-rush of cabin air was experienced when the stair extended and only a one-tenth unit nose-down trim change was required to counteract the airstair floating down approximately 8.5 degrees. The aft entry door was allowed to remain open and a photograph of tuft activity was taken after the airplane
The aft entry door was allowed to remain open and a photograph of tuft activity was taken after the airplane stabilized on this condition (Page 7 ). The tuft picture appears to indicate some airflow into the cabin.
With the flaps still at 25 degrees and at approximately-125 knots airspeed, the airstair was successfully retracted and the uplatch secured by moving the control handle from the UP to the RETRACT position, depressing the handle trigger, and moving the handle back to the UP position after the airstair was fully retracted. The next condition involved extending the stair utilizing hydraulic power. The control handle was moved from the UP to the DOWN position with the handle trigger depressed. With hydraulic

pressure on the DOWN side of the actuator, the airstair initially extended to approximately 14 degrees and then retracted slightly, probably because of compression of the lower struts. Three-tenths of a unit nose down trim change was required with the airstair in this position, but no control problems were experienced (Reference tabulation on Page /0). The aft entry door was open throughout this condition and another picture of tuft activity was taken (Page 8 ). This picture is not as clear as the first because the flash bulb failed to operate.
Following this, the control handle was returned to the UP position, allowing the airstair to free-float, and the aft entry door was closed. The flaps were then retracted to zero and the airplane retrimmed at approximately 200 knots airspeed and 10,000 feet altitude. Engine power was then increased to MCT and the airplane was accelerated to VMO, re- trimming each time the stick force reached approximately 20 to 30 pounds. The free-floating stair oscillated a maximum of 1.5 degrees during the acceleration, but no extreme bouncing was observed (Reference plot on Page // ).
5 degrees during the acceleration, but no extreme bouncing was observed (Reference plot on Page // ). No control problems were experienced during the acceleration, and the airstair slowly retracted as the airspeed increased. Another picture of tuft activity at Vio was taken through the aft entry door window (Page 9 ). Although the field of view is quite restricted, again the tufts appear to indicate some airflow into the cavity. This inflow of air was also noticed when the aft entry door was unlatched at VMo and some inflow of air was noted around the door seals. The door was again latched and the airplane decelerated to approximately 260 knots airspeed, at which time the aft entry door was easily opened, the aft airstair was again successfully retracted and latched, and the entry door closed.
The procedure during Test 100-3 was the same as Test 100-1, except that the airstair was not extended using hydraulic pressure. In addition, the airplane was being continually retrimmed during the acceleration to VMO, making it easier to hold a nearly constant altitude (Reference plot on Page
In addition, the airplane was being continually retrimmed during the acceleration to VMO, making it easier to hold a nearly constant altitude (Reference plot on Page /2 ). An additional condition was also conducted during this test: namely, two attempts were made to unlock the airstair and allow it to free-fall at an airspeed of approximately 300 knots. This condition was done after accelerating to VMo with the stair down. The aft entry door was easily opened at this airspeed, again noting a slight inflow of air into the cabin. The airstair was successfully retracted with hydraulic power and the control handle moved to the UP position to lock the stair. Following this, the handle was moved to the DOWN position, without depressing the handle trigger, to permit the stair to free-fall. Although the uplock was visually observed to rotate and release the stair and the pilot reported that the warning light in the control cabin indicated the stair was unlocked, the air load prevented the stair from extending. A second attempt was made at this airspeed, after first returning the control handle to the UP position and then positioning it to DOWN.
A second attempt was made at this airspeed, after first returning the control handle to the UP position and then positioning it to DOWN. The same results were obtained. The test was concluded by again closing and

latching the aft entry door at the airspeed of approximately 300 knots. No, further pictures of tuft activity were taken on this test. Since no large pressure surges had been recorded in the cavity during Test 100-1, all of the production airstair cavity panels were installed during Test 100-3. No panel movement or oil-canning was noticed during the test, and no panel failures were noted after landing.
CONCLUSIONS
No unusual control or handling problems should be experienced if the aft airstair should accidentally extend inflight. In fact, from the results obtained during Test 100-3, if the up-latch failed at normal cruise speed, the aft airstair would probably not extend until the airplane slowed down to some
In fact, from the results obtained during Test 100-3, if the up-latch failed at normal cruise speed, the aft airstair would probably not extend until the airplane slowed down to some airspeed below 300 knots. The control handle would be expected to remain in its normal UP position, because the detent provides a positive stop. Thus, the first indication of latch failure would occur when the airstair extended far enough to operate the stair warning light microswitch located at the aft end of the cavity. Since the airstair might contact the runway as the airspeed decreased after landing, the aft entry door could be opened and an operator could safety initiate stair retraction. Provided there was no structural interference from a failed roller or up-latch, the airstair should retract. However, it would be necessary to hold the control handle in the RETRACT position and keep the trigger depressed, because the system is depressurized when the control handle is in the UP position.

1 S. LEWIS WALLICK, a Test Pilot employed by The Boeing Company, Seattle, Washington, telephone 655-4031, furnished the following information:
He was the Chief Test Pilot on the Boeing 727 project and he conducted the flight testing of this aircraft.
On several occasions during this testing he intentionally lowered the rear stairs under the tail of the aircraft while in flight" The effect of lowering these stairs in flight was hardly noticeable on the controls and the only positive indication he had that the stairs were lowered was - the lighting of an indicator light on the instrument panel.
while in flight" The effect of lowering these stairs in flight was hardly noticeable on the controls and the only positive indication he had that the stairs were lowered was - the lighting of an indicator light on the instrument panel. The stairs were lowered at a speed of 150 knots. While the stairs were lowered the plane remained in the same attitude. There was no yawing or pitching/
He furnished the following opinions in connection with the question of whether or not a pilot would feel in his controls a sudden loss of weight of approximately 180 pounds from the tail of a 727? He advised that if the pilot were flying the aircraft manually and if the air were calm, he would feel a sudden loss of 180 pounds weight from the tail of the aircraft ; He explained that the loss of this weight would move the center of gravity toward the front of the airplane and while this movement would be slight, it could be felt in the wheel by the pilot: He stated, however, that if the air were turbulent, it is doubtful that the pilot would feel this sudden less of weight: He indicated also that if the plane were being flown on auto-pilot the loss of this weight would not be felt by the pilot.
He stated, however, that if the air were turbulent, it is doubtful that the pilot would feel this sudden less of weight: He indicated also that if the plane were being flown on auto-pilot the loss of this weight would not be felt by the pilot.
He advised that if the rear stairs on a 727 is lowered in flight at an altitude of less than 10,000 feet a . change in pressurization occurs and this could be felt by the crew if the door leading into the cockpit is open? If the cockpit door were closed, it is doubtful that the crew would experience the change in pressurization 3

The two parachutes recovered from the Northwest Airlines flight 305 at Reno, Nevada, on November 24, 1971, were described in detail to Mr. COSSEY at which time he described the missing back pack parachute as having a sage green nylon container, model NB6 (Navy Back pack 6) with sage green nylon harness, which harness has no "D" rings to mount a chest pack. The parachute is a 28 foot nylon white flat circular with a specially fitted foam padded cushion. The pilot chute is also white.

COSSEY said that the missing chest pack para- chute is a ground training pack dummied up to look like a good one. He said that by "dummied up" he means that tie downs were attached to the container. This chest pack was devised by COSSEY to teach trainees while hung in a harness how to open the chest pack in the event of an emergency. The folds of the parachute are sewen together to preclude the parachute opening in the training room. Mr. COSSEY said that the back packs furnished the hijacker did not have the necessary hooks on the harness to attach a chest pack.

as it would be impossible to hold anything in his hand when the parachute opened. Mr. COSSEY said it would be quite possible to parachute from a 727 jet if the jet was below 10,000 feet and flying at a very slow rate of speed. The person jumping from the plane would have to free fall to earth for several thousand feet to slow himself down and get himself in position for the back pack to open. Even an experienced parachutist would experience considerable shock from the chute opening, however, this would cause little or no personal injury. He said that anyone who had six or seven practice jumps could accomplish this as the first five jumps would be on a static line and the subsequent jumps would be free fall.
He said that jumping at night materially increases the chance of injury and in this case he would consider the parachutists chances of not being injured as "nill.
He said that jumping at night materially increases the chance of injury and in this case he would consider the parachutists chances of not being injured as "nill." Mr. COSSEY said the back pack used by the hijacker is non-steerable and he would have no chance of slowing down or picking the spot on which to land. Also at night he would be unable to gauge his distance to the ground which would result in a much harder impact. It was his opinion the skyjacker would suffer severe ankle and or leg injuries from this jump.
Mr. COSSEY said that the fact the hijacker wore street shoes would also increase the chance that he would be injured on landing as the most experienced jumpers wear jump boots or some rigid ankle support.
Mr. COSSEY expressed the opinion that the pilot of the jet would notice some oscillation when the hijacker departed the rear of the aircraft.
