Oh and I was stationed at MCAS Miramar... which used to be NAS Miramar.... which is where the film was shot/based on
Aircraft sorties or "flights" are constantly checked. Different parts have scheduled maintenance based on flight hours.
More importantly, the maintenance manuals used to maintain parts are constantly being revised. When I was in the military, shyt would fall off, or bombs would drop and be duds. People don't realize how important and expensive maintenance is when it comes to aircraft.
Flying used to be a luxury. And event. Now it's become something that's taken for granted.
