Boeing 247

The **Boeing 247**, sometimes called the **Boeing Model 247** was an American airliner. It is thought to be the first airliner to fully use advanced things like retractable landing gear, an autopilot and deicing boots.

The Boeing 247 first flew on February 8, 1933. It started being used later that year. Later, planes became bigger and some had four engines. However, no big changes were made until Boeing made the Boeing 307 Stratoliner.

## Design and development
The Boeing 247 was an advanced plane. The design was taken from the Boeing Monomail (Models 200, 221, 221A) and the B-9 bomber. The Boeing 247 was faster than the Boeing P-12, which was the main American fighter at the time. The P-12 was did not have a roof on the cockpit, and it was a biplane. The Boeing 247 landed at just 62&nbsp;mph. This meant that flaps were not needed. At just 10&nbsp;mph, the back wheel came off the ground, which made it easier to steer.

Also, the 247 was the first airliner with two engines which could fly on just one engine. The Boeing 247 had special propellers. It could fly at 11,500&nbsp;ft at full weight. The Douglas DC-1 and some other airliners before World War II used parts of the Boeing 247's design.

The pilots did not think that the plane, which weighed eight tons, could land on any runway back then.

Boeing wanted to make the plane as safe as possible. They made the plane strong and put in things to make passengers more comfortable. For example, the cabin had air conditioning. It was also sound-proof. The plane had a pilot, co-pilot and a flight attendant. The wheels did not fully go into the plane. A part of the wheels hung down below the plane. This was done to make it safer for the plane to land if the landing gear could not be put down. The wheel at the back of the plane could not be moved.

## History
In 1934, Boeing put a Boeing 247 into the MacRobertson Race. In the race, planes raced from England to Australia. The pilots of the Boeing plane were Col.Roscoe Turner and Clyde Pangborn.

The Boeing 247 won the 1934 US Collier Trophy for "excellence in aviation design".

The 247 could go across the United States eight hours faster than any plane which came before it. The Boeing 247 started being used on May 22, 1933. One set a record of 19½ hours when it flew from San Francisco to New York City.

The first 60 247s were sold to Boeing Air Transport (part of the United Aircraft and Transport Corporation, UATC). They cost $65,000 each.

The 247 was used until World War II. The Royal Canadian Air Force (RCAF) had seven 247s to move soldiers around. Some 247s were still flying in the late 1960s. These were either cargo planes or personal planes.

November 9, 1933 - A United Air Lines 247 crashed after it took off. Four of the nine people on the plane died.

December 20, 1934 - United Air Lines Flight 6, a 247, crashed near Western Springs, Illinois. Nobody died. The plane was fixed and started flying again.

October 7, 1935 – United Air Lines Trip 4, a 247D, crashed 10 miles to the west of Cheyenne, Wyoming. It is not known why it crashed. Everybody on the plane died.

October 30, 1935 - A United Air Lines Boeing 247D crashed near Cheyenne. Everyone on board died.

December 15, 1936 – Seven people died when Western Air Express Flight 6, a 247D, crashed on Lone Peak in Utah.

December 27, 1936 - United Air Lines Trip 34, a 247D, crashed in Los Angeles County, California. All 12 people on board died.

January 12, 1937 – Western Air Express Flight 7, a 247, crashed into a mountain in Newhall, California. Five people died.
