- I don't know for sure, but I believe almost all of their avionics are in
- pressurized bays. There isn't much unpressurized space in a pressurized
- airliner, except at the extreme nose and tail.

-
- Very few military jets ever get up to 70,000ft. 50,000 is a more typical
- ceiling for reasonable configurations. Only the specialized ones can even
- reach 70,000 except in a ballistic trajectory.

- >I think the blackbirds cruise at 100,000 ...
-
- This is popular mythology, but so far as I know it has never been confirmed.
- The openly-admitted Blackbird altitude records are in the 70-80 range.
-
- >Actually could a blackbird pilot get astronauts wings? on some sort of ballistic shot????
-
- It's most unlikely. All of the altitudes we're talking about are *way*
- below "astronaut wings" altitude. And the Blackbird is not particularly
- well-suited to ballistic trajectories; the ballistic-trajectory altitude
- record is held by the F-15, not the Blackbird, and it's only about
- 100,000ft.

-
- Please read what I wrote, Pat! On the later lunar missions the SM had one
- bay full of remote-sensing equipment, and they needed to recover film from
- it. There were no such EVAs on the earlier lunar missions.
