Cobra, The airplane may have come in on an allnighter-the fuel in the tanks can be extremely cold. Depending on the temp/dew point spread, frost can then occur at temps you would't expect it to. The frost on the underside of the wing is allowable to an 1/8th of an inch-but none can be on the topside...

Wow Raymond. You keep stating ACPA like it is a foreign entity to you or something. You were ACPA. You were the MEC chair. What a golden opportunity to have introduced your enlightened thoughts on discrimination/forced retirement. I used to listen to your phone in messages. The subject never came up...

Remember, don't wear sandals!

51 is just the beginning guys. They didn't want to publish a huge bid prior to the November Judicial review vis a vis retirement.
Hang in there..despite what some say, all the BS etc etc...it's a great place to work.
