As a C-130 Flight Engineer we frequently went to locations that had no real airfield (no lights and definitely not paved). At one location the people that ran the place made it a game to see if they could get a crew to stay in "tent city" over night.
The rules were that if we could not take off before sundown, we had to stay the night.
We landed just before sundown and the ground crew was taking its time unloading, for obvious reasons. They had nabbed one of our crews a couple of days earlier so we were onto their game. But, we didn't say a thing other than acting like we wanted them to hurry up and get us unloaded so we could get out of there.
Sundown came and went. They finally finished unloading us about 20 min after sundown. We closed up the doors and taxied back to the end of the runway. Called for clearance to take off and of course were told the field was closed due to no lights. We told the controller we didn't need lights, just approval to go. He still didn't get the hint but played along with us and gave us approval.
We put on our night vision goggles, hit the gas and off we went.
Rules state that two primary crew members must be nvg qualified to do take-offs and landings. We had 3, Pilot, Copilot and me.
Guys on the ground were PO'd. We heard about it the next day at our morning briefing and just told the CO we had the goggles and off we went. He laughed his ars off.
Next time we went into that location the guys didn't even bother trying to drag their feet unloading us. Our squadron also made it a policy to only send in nvg qualified crews just in case.
