He posted a link; seems some (allegedly) UCH F/As dressed for Halloween as injured Asiana Flight Attendants.

If true, it's relevant to UCH. I had to delete the link for TOS, but left some information if you want to look it up on your own.

I'll say what they did was in pretty poor taste, and if the allegations are true, their jobs are in jeopardy. (As fly4fun implied).
