Aspen 20, I show you at one thousand eight hundred and forty-two knots, across the ground.

And the space shuttle flew at over 5 miles a second while Apollo 8, 10 , 11, 12 13, 14, 15, 16 and 17 flew at over 24,000 mph. Now that is fast. The SR-71 was a slow poke compared to them.

Atmospheric drag plays a part.

Shul’s “Speed Check” story is about ATC (Air Traffic Control). The Space Shuttle and the Apollo flights did not talk to ATC.
