Many moons ago we were doing some wiring checks under the pedestal console on a BH212. We found a brown stained and brittle envelope addressed to GMAC Financial. We figured some offshore guy must have given it to the pilot to mail for him when he got back to base and it slipped and fell into an opening at the base of it. I don’t remember it was ever put in our outgoing mail, but I’m pretty sure the offshore guy got a late payment notice. The word was put out not to accept mail from offshore folks unless it was company business.
