I remember the air crewmen putting as many as 20 chains on aircraft in heavy weather.
In today's navy:
"Where are all the chains for this aircraft?"
"Umm, we borrowed them."
"For what?"
"For the dungeon."
"The what?"
"The dungeon. The B and D folks set up a dungeon on the bottom level so they can get their rocks off doing what they love best."
"And the CO knew about this??"
"The CO is the dungeon master."
"Oh, Christ. Go bring the chains up here. We need 'em for this storm that's coming up." (Sigh...)
