Junkers Ju 87 below 3g and had lasted no longer than three seconds. In a crouched position, pilots could withstand 7.5g and were able to remain functional for a short duration. In this position, Junkers concluded that ⅔ of pilots could withstand 8g and perhaps 9g for three to five seconds without vision defects which, under war conditions, was acceptable. During tests with the Ju 87 A-2, new technologies were tried out to reduce the effects of g. The pressurised cabin was of great importance during this research. Testing revealed that at high altitude, even 2g could cause death in an unpressurised cabin
Junkers aircraft engines, albeit in the absence of its founder, who had been removed by the Nazis in 1934. The history of Junkers aircraft production begins with the Junkers J 1 mid-wing monoplane (not to be confused with the later, all-metal sesquiplane ground attack aircraft with the "IdFlieg" designation J.I which had a factory designation of J 4). Research for this aircraft began in 1914 and was interrupted by the start of the First World War. The prototype aircraft, named the "Blechesel" (Tin or Sheet-metal Donkey), was completed in very late 1915 after the outbreak of the war. This aircraft is
