Why is the Boeing 757 undercarriage so high?
Rotation angle at takeoff is often the limiting factor in gear height. The 757-300 is 178ft long, 30ft longer than the Airbus 321 which also has tall landing gear. The first 737s were less than 100ft long, which allowed the short gear and later caused problems with the max9/10 stretches which went to 143ft.
