On This American Life, the recent Nice Work If You Can Get It episode, they interview astronauts.

Apparently, when astronauts return from a space mission, they have to fill out an expense report.

The box you check for space shuttle is “Government Air”.

High-larious.

They are alloted $3.50/day for incidentals. You know, in case they have to pick up dental floss while they’re up there.
