"Airplane means an engine-driven fixed-wing aircraft heavier than air, that is supported in flight by the dynamic reaction of the air against its wings.
Question 1 : what's an aircraft?
Question 2 : what about lifting bodies? they don't use wings, they use their fuselages, but they still abide by the pressure difference law so i guess it doesn't matter.
as wing the folding/swing wing issue, i guess it depends on what is used when. if they are on the ground then they could be anything; like we could be airplanes, technically. but if we fell out of the sky, we wouldn't be planes, we'd be dead.
, if you were in a vehicle cruising @ M12.0 and FL2000 while running on scramjets, would you be in an airplane?
See whenever i talk about hypersonic flight in here, most people assume and conclude
that i am refering to space flight (which sounds like an oxymoron) and nothing in between, so i thought maybe my definitions were off.
The meaning of life is curiosity; we were put on this planet to explore opportunities.
