"I Feel The Need . . . The Need For Speed!"

Edwin; I like that shuttle-on-747 stamp. It was painful when I purchased it, but it's cool.

As many times as I have seen it, how does that 747/Shuttle combo fly?

Engines

Four Pratt and Whitney JT9D-7J gas turbine engines, each producing 50,000 lbs of thrust.
Performance

* Airspeed limits with, and without an orbiter: 250 knots or Mach 0.6
* Altitude: Typical cruise with orbiter, 13,000-15,000 ft; typical cruise unmated, 24,000-26,000 ft. Minimum temperature at altitude 15 degrees (F) (-9 degrees C)
* Range: Typical mated, 1000 nautical miles (with reserves); maximum unmated, 5500 nautical miles

Yeah, I knew that . . .
