No. Airplanes don't do anything to gravity. a plane experiences the same force from gravity of any other object of the same mass, whether it is flying or on the ground. When a plane is flying the air passing over its wings exerts an upward force great enough to lift the plane.
About 9000 planes fly at the same moment
Airplanes are generally fixed-wing aircraft. Aircraft can mean any type of flying machine, from airships (balloons/blimps), jets, propeller driven airplanes, rotor-wing (helicopters), UAVs (Unmanned Aerial Vehicles), drones (about the same thing as a UAV), or the space shuttle.
All gliders are airplanes, but not all airplanes are gliders.
There's really no such thing as flying "on longitude". Do you mean that they stay on the same line of longitude when they're flying ? That would only be true as long as an airplane is flying exactly due north or due south. Any other time, it's flying through plenty of different longitudes.
Birds and airplanes both have wings.
1000 cause they were flying
airplanes are the same thing as hovercrafts... but only hovercrafts have a louder engine
An airplane is a flying car. cars trains airplanes etc. are all basically the same thing. theyre ways of transportation, just larger or smaller etc. they all have most of the same necessary parts.
The US Navy, as well as the navies of other nations make use of airplanes. The airplanes are often deployed from aircraft carriers. The navy does not necessarily have the same types of or capacity for airplanes as, say, the Air Force.
Great Britain had the same kind of military equipment as many other countries. Guns, tanks, and airplanes all aided in the war effort.
