Does anyone have estimates of the Shuttle's:

1) "Indicated" Airspeed (i.e. taking #2 into account)

2) Density Altitude

3) Are these terms from low-altitude aviation meaningful in near-space?

" 1) "Indicated" Airspeed (i.e. taking #2 into account)

They're going ~1000mph, ~mach 1.33.

" 2) Density Altitude
3) Are these terms from low-altitude aviation meaningful in near-space?

They're still in the atmosphere. The time of flight to that point was 81secs. They are not in near space.
