The president
In an air-brake equipped vehicle, the primary air system supplies service braking pressure to the drive axles of the vehicle, and, if applicable, supplies service air to the trailer axles when the foot valve is used for braking.
The british air force is known as the RAF; royal air force. The Deutsche Luftwaffe or Luftwaffe (German: "Air Arm", IPA: ['luftvafə]) is the commonly used term for the German air force.The Royal Air Force. They are still called this today.
The plane used to transport the President is always called Air Force One, irrespective of which particular plane he's in. It is generally a Boeing 747-200 modified with special equipment such in-flight refueling. To be more technical, it is Air Force One if he is on an Air Force Plane, Marine One when he is on the helicopter, or Navy One if he is on a Navy plane. The "one" gives the aircraft priority in aviation hierarchy (the smaller the number, the higher the priority).
There have been multiple Air Force Ones made for different presidents, but the first one was made in between 1938 and 1941 for Franklin D. Roosevelt. He was the first president to fly in an aircraft. This plane is on display at the Air Force Museum in Dayton Ohio, and you are allowed to walk through it, and even look at the little elevator they used to get him in and out of the plane in his wheelchair.
None the wind keeps the glider in the air
Gliders are pulled by a small plane into the air and then the gliders move around catching air currents from the heat.
Gliders and hot air balloons have no engines. (also paper darts, if you count them!)Gliders
Hand gliders use to be used in space for transportation. )Before used on earth)
A plane without an engine is called a glider. There are many varieties of gliders, but they're generally used for air sports such as gliding, hang gliding, and paragliding. There are, however, military gliders, which have also been used in times of war.
if you have a helicopter or a military grade hoover craft Hot-air balloons and gliders can be used
Keyblade gliders are a vehicle used in birth by sleep that "glide" around.
Airplanes have engines, gliders don't and must be towed up in the air in order to fly by a tow plane.
Gliders soar better when its not too cold because warm air promotes better lift whereas cold promotes more drag. Warm air rises higher than cold air does.
Videos of hang gliders soaring through the air are available directly from YouTube. Users upload hundreds of hang gliding videos to the site on a regular basis.
Zero.
Gliders use no energy but they do use an airplane to tow it into the air.
