How big is the hangar, how small are the airplanes.
Airplanes fly in the troposphere, which is the lowest layer of Earth's atmosphere. This layer extends from the Earth's surface up to an average altitude of about 11 kilometers (7 miles).
A change in the Earth's mass would not directly affect the banking of airplanes or roadbeds. The banking of airplanes and roadbeds is primarily determined by the design and engineering specifications specific to each mode of transportation, and not directly influenced by the Earth's overall mass.
Four airplanes were hijacked on 9/11.
