They're on our secure flightline right outside my office, so I doubt it. There's a T-34B parked between them now.
Why would somebody need to stay with them all night? There's IRCM on almost every prop/chopper in the Marine Corps, including our newer OSA aircraft. Never been a problem.
I'm just surprised LAMPS would let them do that. They're treated as SECRET. I also had my tongue planted in my cheek for that entire post.
