Come on Mr. Dog, I understand when you throw a ball up in a moving car you can catch it. This is not what i'm talking about. Simply tell me why I can't catch that same ball if I throw it up while on on the back of a jet plane, flying in the sky. The conditions are the same as the Earth only NOT relative to the Earth because of the planes height above the Earth, same speed and same direction, (west to east). Also, the plane is flying in the Earth's atmosphere on a very calm day, so it would feel the same atmosphere as a person feels on Earth, hardly any breeze at all. Please explain your answer in layman's terms.
Is the plane going the same speed as the Earth (464 m/s) in the same direction as the Earth is spinning?
Yes, Mr Dog. The plane is exactly simulating the Earth in all regards. In fact you could say it is geostationary. Only it is not in space. it is in the atmosphere. Because the person is riding on the back of the plane, they would be in the same system as they would be as if they were on the ground on a fine day. They should be able to stand up and walk around the plane's back without even falling down or be blown off by the wind. The samme as we do on Earth. Can you picture what I mean and do you think my assessment is correct?
Airplanes, with very few exceptions, can't hover, which is what you're describing. If you're on top of, say, a hovering
V-22 Osprey, then, sure, you could stand up and walk around on top of it (presuming you can avoid the downwash and turbulence from the props, and the plane was steady enough). Why wouldn't you be able to do that?
Traditional fixed-wing aircraft generate the lift they need to stay aloft by flying
through the air at high speed. If airspeed is zero, the plane falls out of the sky because there's no lift, so what you describe can't happen (absent a headwind strong enough to be above stall speed); even if the groundspeed is zero, your airspeed must be well above it.
You
can stand and walk around in an open basket suspended below a hot-air balloon while aloft. Because those
do hover if there's no wind, as you describe. You're riding along, suspended in the air, over a fixed spot on Earth. If there is wind, you move slowly over the Earth along with it.
