Pilots have to adjust their flight paths to compensate for the Coriolis effect.  This is something we can calculate.

No. Theoretically the upper limit of the weight of a flyable being is around 12kg.

A plane would only have to travel at approx 1000mph to go around the Earth in 24 hours.  Some supersonic jets easily travel that fast.  Throw in time for slowdowns to meet with tankers and landings to refuel.  I believe that it can be done.  I'm surprised that the government didn't have the Sr71 attempt it during its career.

the side length is 2\nso the altitude should be 3^(1/2)\ngood luck

There are pilots on the ground.  They fly by remote control.  Read more about it below.\n\nVery, very few can fly without some human intervention.

If your claim was really true, you must be an aeronautical genius.  You'd be too smart wasting your time asking this on some goofy anonymous website like this one.

The U.S. government has many such secret anti-gravity aircrafts which they test in the western U.S.   This is one of them that you and your friend saw.  See the attached link for a picture.

Probably not. That hot point of light you see is not just an arbitrarily small spot, it is an image of the sun projected onto the surface. It is smallest when it is in focus, which only happens if the distance from the lens to the surface you are projecting onto is equal to the focal length of the lens. So to do it from high up in an airplane, you need a really long focal length lens. Trouble is, doubling the focal length of the lens doubles the diameter of the image it projects, which cuts down the intensity of light in that image four fold. To keep the same heating, you need to increase the diameter of the lens by the same amount that you increase it's focal length. So if a 3 inch lens with a 6 inch focal length burns paper 6 inches away, you would need a 300 foot wide lens to get the same heat from 600 feet away. 600 feet is pretty low for an airplane and 300 feet wide is a pretty big lens to carry on an airplane, don't you think?

Certainly possible in theory. I doubt if anyone has ever done it in practice.\n\n\nRemember that a plane stays up in the air because of the speed that the air moves over its wings, not beceuse of how fast the plane moves relative to the ground. If a plane turns into the wind it can generate the same lift while travelling slower relative to the ground. With a strong enough headwind it is quite possible for a plane to remain stationary and airborne\n\nBut as I said, this is only theoretically possible. I've seen light planes do this and hang-gliders and birds do it all the time. But it would be incredibly dangeorus for a 'passenger flight'. If the wind were to drop, even for amoment, the plane would immediately stall and fall from the sky. It's fairly easy for a light plane or glider to recover from such a stall, but a large commercial passenger craft would find it much harder. There's a good chance it would crash.

Dont know about in the USA but in the UK airspace is "such height as is necessary for the ordinary use and enjoyment of the land and the structures upon it" Lord Bernstein of Leigh v Skyviews & General Ltd, and the ground under land is owned although any minerals found will likely be owned by the state
