No, you are really imagining them.
12km and above is the stratosphere . Human life cannot exist with that air pressure.The airplanes stay just to the peak of the troposhere.
nothing they didn't and they never will that's why airplanes don't exist -_-
Indoor RC airplanes do not exist due to regulations. As you might note, manufacturers are required to list the age range of the toys and specify that they are to be used outdoors.
There was no need for airports during the 17th and 18th century because there were no airplanes.
If gravity did NOT exist, then we all would be floating in mid air and would float into things, like airplanes. Plus, then if we fall, we would be in outerspace. COOL!
Concepts of flying machines existed, but the first powered flight by an aircraft didn't occur until 1903.
No, the air is what allows for lift. The only way an airplane can "fly" without air is if the downward force of gravity didn't exist.
Yes, jets really are airplanes but they are faster airplanes.
All gliders are airplanes, but not all airplanes are gliders.
Yes, jets are airplanes but they are called supersonic airplanes.
airplanes are cool
Yes, airplanes are aircraft. However, not all aircraft are airplanes. Helicopters, blimps, and balloons are aircraft- but they are not airplanes. Airplanes are generally fixed wing machines that move through the air.
