tnkrdrvr,
Yea, it's one of those things. Back in the 70's it was when pilots started having long hair, meaning something other than a high-n-tight cut. I think Flying the Line Volume I had a few paragrphs on some pilots who bucket the system.
It's a late post, spent the whole friggin day in the yard.
