All astronauts should be midgets.

The other thing is that being an astronaut involves reaching a large number of switches a good distance away from where you're strapped into the seat. If they could ever get all those flight controls and indicators and alarm lights and cut offs and all that stuff into the arm region even one average size human being we could get rid of an entire separate second pilot except for you know the backup purposes. But literally, just for user interface standpoint the cockpit of a non-trivial aircraft takes up a lot of manual geography. Even in a light plane as a 5 ft 10 guy a lot of things were questionable out Of reach involving a good bit of stretching to get to some things. And I've said in a what 787 cockpit. Know that number is too high he was a seven something seven. And lots of stuff was barely within reach. I can't imagine it's any better in a space shuttle.
