"Guys who hang around being useful may get some stick and teasing initially, but they soon get to understand the language and culture of aviation. And then they start to fit in"
Guys need a security pass to go airside. They need a reason to get one, and it costs money. Not a chance.
Just after the Seattle turboprop theft and suicide, I was kept waiting in the hangar beside the aircraft I shared with a senior airport manager who had an "access all areas badge".
Security had refused to let him through as he was not scheduled to be working that evening.
(He had to contact the duty manager to get in.)
