So for sake of argument, even if the ground speed was half the true air speed (I don't believe it would even come close to making that much of a difference), this would make the ground speed 1,100mph. This would be 2.5 miles every minute, and 222.6 feet per second of earth curve; the plane would have to decend this much to not fly off into space.
For another example, take a commercial Jet going 600 mph ground speed. They usually go slower than this, but they are capable of these speeds. That would mean the jet goes 60 miles every 6 minutes. The jet would have to decend 2400 feet every 6 minutes; and they typically fly around 35,000 ft altitude. Does this sound plausible?
Given a spy plane flying at 70,000 feet follows a larger circumference of a circle, than the earth's circumference at sea level. But considering how large the earth's circumference allegedly is (24,901 miles), this would not be a real significant difference.

*Descend... If you really wanted to promote your flat earth theories, you'd choose an argument that isn't so laughably ludicrous.
