Take off speed is different for different aircrafts. There is no one speed for all aircraft. Usually depending on the load etc, take off speed would be the speed at which enough lift is generated to enable the aicraft to lift off the ground.
The answer to this one is no. Yes a plane does have to be traveling at a certain speed in order to lift into the air. But as long as the aircraft maintains that speed it can either climb or descend. The speed merely determines how fast it climbs.
the flaps on a plane increase drag and they create lift so the piolt can fly the plane at a lower speed.
Because it's speed generates lift on the wings.
That is called "supersonic".
The first plane was the experimental Ball X-1.
ultra sonic !!
The X-15
Yes there is a specific fuel needed to fly a RC Plane. This fuel is: Rapicon Max Power RC Airplane Fuel 15% You can buy it here: www.amainhobbies.com
In theory, any plane can fly around the world in an hour, regardless of size or speed. It depends on your definition of 'around the world'. No existing plane can do this at the equator. But any plane can fly along a line of latitude that has the same full length as the distance the plane can fly in one hour. The faster the plane, the farther from the poles its lines of latitude will be.
A complete change in the "laws" of physics!
Because of the speed that the plane flies.
About 600 mph.
