NAVY OFFICERS SEE
new BOMBER TEST
Remarkable" Feats Per-
formed by "Martin "a" on
+ AnaC0Stia Field.

The dreams of aeronautical en-
gineers. which have pictured bomb
ing plane that could perform like
small combat ship and still carry
heavy load of deadly missiles, came
sten closer to realization here yester-
Gay afternoon when the Martin "a.
new singleengined bomber, was given
a private flying demonstration at the
Naval Air Station Anacostia, before
ranking officers OF the Bureau OF
Aeronautics.
With Lieut.. S. w. Galloway,
member of the Navy's flight test
board at the controls, the bomber
Ieaped into the air after a run on the
ground of but 6 seconds and went up
in a climbing turn without going be-
yond the edge of the field. Lieut.. Cal
Iaway then demonstrated it's maneu-
variability by rolling it from side to
side. pulling the nose up at a sharp
angle and climbing all the while, and
ended his flight with few wing
overs the closest approach to loop
in acrobatics.
Rear Admiral William A. Moffett,
chief, and his assistant chief of the
bureau, Capt Emory S. Land; Comdr.
Fngene i. Wilson, head of the design
section of the bureau. and other prom
inent naval air officials, were out
spoken i'm their praise for the flying
ability of the plane. which they char
acterized as remarkable.
First Official Parade.
While the plane made it's maiden
f7iaht in Cleveland a few days ago, the
trims aloft yesterday marked the first
parade before naval officials who have
been searching far and wide for a
hop,bpr t0 he carried aboard the new
aircraft carriers.
An added feature of the planes per-
formance was that the power plant

The ship was designed and built by
Glenn L. Martin of Cleveland, a
pioneer aircraft builder. So convinced
was Mr. Martin that he had the
answer to the cry of the Navy for
carrier-bomber that he personally in
vested a sum in excess of Sl50,000 to
build the plane and run the risk of

1900 pounds. In that capacity, it is
1000 pounds lighter than the present
torpedo and bombing plane used by
1.-The Navy and which is fitted with
Packard S00-horsepower engine. Its
top speed is 100 miles an hour and it
can cruise for 8 hours on one charge

AIi-Metal Frame.

the wings. is of all-metal construction
THE bomber's cockpit is in front, i'm

pflot sits behind the bomber. A few
feet back on the fuselage the machine

squirmed all over the sky until the
smaller plane finally abandoned the
undertaking.
