Ahhh....dunker training! I had a session of that too. ...
Over the years I've had a few sessions of that along with real helo hoists at Pensacola, NAS Jacksonville and NAS North Island, Miramar -- lotsa fun

Why do I always do this training in January?
Edited to remove references which date me 
lol
unimogbert -- we got to do the "rollover helo trainer " 4 times, twice wearing opaque goggles.
NightHiker -- most everything is easier when you stay calm.
