but I believe that the actual airspeed of a plane at 85,000 feet with a measured ground speed of 2,200 mph is higher than 2,200 mph (simple spherical geometry).
The difference due to spherical geometry is insignificant--you'd only be 16 miles above a sphere (the Earth) of radius 4000 miles.

But let me understand this, are you seriously suggesting that the Blackbird has actually flown at 22 thousand miles per hour?
