Airplanes fly under their own power which means they can have a sustained flight until they deplete their power source - as opposed to gliders that maintain flight by an initial exterior power source and airships that fly by being buoyant in the air, or floating like a ship on water. also planes fly by producing lift on wings or a lift producing body (a lifting body) - as opposed to a missile that flies entirely by its power source being greater than gravity, friction and other forces acting against the flight or by being "pushed" by external forces like a glider to overcome the same forces. Helicopters are airplanes as the rotor is a spinning wing so they fly under their own power and produce lift - if you have ever seen one of the small aerobatic aircraft that can "hover" in vertical position it is still acting as an airplane since the prop is now acting as a spinning wing - but one of the new fighter jets doing the same thing would then become a powered missile rather than an airplane since it is no longer producing any lift. The term aircraft can refer to any of these types that operate in an air environment: airplane, glider, airship or missile.
All gliders are airplanes, but not all airplanes are gliders.
Yes, jets really are airplanes but they are faster airplanes.
airplanes are cool
Yes, jets are airplanes but they are called supersonic airplanes.
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.

Something about airplanes
No, there were no airplanes in the Victorian era.
Airplanes are kept in hangars.
Yes, they had airplanes in 1907. Flight in airplanes began about 4 years before that.
People use model airplanes because they like airplanes or the look of them.
We can find airplanes in the airport
