I flew the -100 and -200 at Evergreen. We were shown a training film (TWA) with a "pilot" using the reel, similar to the Lufthansa film shown here. The instructor had been a long-time TWA indoc instructor.

After the film, the instructor told us the "pilot" was in fact a Hollywood stuntman in a pilot uniform. Not shown:

When he hit the ground, he had a dislocated shoulder.

We also had the "diapers." Rubberized canvas shorts you could hook the reels to with clips (you could do either hand-hold, or connect to the shorts).

Neither one sounded enticing, but I figured if I needed it, I'd rather use the pants, than slide down a razor-blade.
