No.
Commercial jets do. Military jets normally land on military airports/airfields. An example for such an airport is Edwards Air Force Base.
The 747 is lighter on landing because of the fuel it burned off during flight. This is true for all planes.
All sea planes, for example, have to ski for take-off and landing. So what is the point of the question?
Yes, it is possible to take a plane to the Bahamas. The island country in question will clear for landing private and public planes from many origin points as long as proper flight and landing procedures are observed.
Float plane. Bush pilots can fly either standard landing gear or floats.
Yes. It can take-off on auto pilot. But we have to programme it correctly according to the procedure. All commercial airplanes take-off manually.
yes but the 2 airfields were mostly used as an emergency landing for b-29s
not during take-off or landing, the captin should tell you when the plane has reached stabilaty and/or the right elavation
planes can take -84C & planes fuel can take -48C
Yes. The Harrier and the F-35 (JSF) are examples of planes with Vertical Short Take Off and Landing. So these plane can suspend in the air.
the airport tower of where it is landing because then they know not to let other planes land or take off at that time so there is not a crash.
Sea planes are designed to take off and land on water. To do so, they have special floats on their struts. These are called pontoons and they are what makes the plane float on the water.
