Flight Suit Follow-Up

In a follow-up to yesterday's post of the manual for the F3-A electrically heated flying suit, here is where the astronomers would plug in their flight suits to keep warm:

As you can see there is a nice rheostat so that the astronomer could dial in the correct temperature to counter the cold of the night.

Thanks to Drew from the Palomar Day Crew for providing me with this photo! No one has used them in decades, but the rheostat and outlets are still up in prime focus.
