I knew they had some pretty restrictive limits while carrying the Shuttle i'm just surprised the restriction remains when
it is not carrying it.
|Quoting rwessel (Reply 1):|
NASA says 250kts/.60M with or without a Shuttle on top. They don't list a maximum altitude, but mention "typical" cruise altitudes of 13-15,000ft (mated) and 24-36,000ft (unmated). I'd expect that with the huge drag of the Orbiter, and the significant fall-off in engine performance with increasing altitude, the maximum achievable altitude (mated) is not that far beyond the 15,000ft listed.

Trying to find out what the speed / mach and altitude limits are on the Nasa 747SCA with a space shuttle attached for ferry flights.
