What is a Stratoliner airplane?
The 307 Stratoliner was the world’s first pressurized commercial airplane that allowed people to “fly above the weather,” as was commonly said during that time. It flew at an altitude of 20,000 feet, higher than the 5,000- to 10,000-foot altitudes of unpressurized airplanes.
In which year Boeing 307 Stratoliner became the first aircraft with a Pressurised cabin that permitted the commercial flights to fly above the normal altitude?
First flown in late 1938, the Boeing 307 was the first airliner with a pressurized fuselage. It could carry 33 passengers in great comfort and cruise at 6,096 meters (20,000 feet), while maintaining a cabin pressure of 2,438 meters (8,000 feet).

What was the first pressurized airplane?
307 Stratoliner
Then, in 1946 the first commercial cabin pressurization system came into use. Boeing’s 307 Stratoliner – nicknamed the Flying Whale – began flying passengers in pressurized comfort at 20,000 feet. It was the first in-service pressurized airplane and airliner in history.
When did airplanes get pressurized cabins?
While the first experimental pressurization systems saw use during the 1920s and 1930s, it was not until 1938 that the Boeing 307 Stratoliner, the first commercial aircraft to be equipped with a pressurized cabin, was introduced.
How many B-17 were shot down?
Of the 291 attacking Fortresses, 60 were shot down over Germany, five crashed on approach to Britain, and 12 more were scrapped due to damage – a loss of 77 B-17s.
What is the purpose of pressurizing an aircraft?
Cabin pressurization is a process in which conditioned air is pumped into the cabin of an aircraft or spacecraft in order to create a safe and comfortable environment for passengers and crew flying at high altitudes.

Who built the B-17?
the Boeing Company
Developed by the Boeing Company in the 1930s, the B-17 was a four‑engine heavy bomber aircraft used by the U.S. Army Air Force during World War II. It was a very effective weapons system, dropping more bombs during the war than any other American aircraft. Why was the B-17 called the “Flying Fortress”?
Why are fighter jets not pressurized?
Therefore at higher altitudes, cabin pressure in a fighter jet is low enough that supplemental oxygen is required for the pilot(s). This is supplied via On-Board Oxygen Generation Systems. By not pressurizing the cabin completely reduces stress on air frame and is beneficial during an unplanned decompression.
