Tanking

I thought a handful of the world's air forces had a monopoly on aerial refueling. Not so. Apparently, private midair refueling service is a thing (though good luck finding a Gulfstream modified to take on a fresh load of Jet-A over the North Atlantic). Omega Air Refueling operates a small fleet of air tankers to support Navy and Marine aviation, "as well as Foreign Military or specialized industry R and D projects."

Somehow, this is a Spycraft thing.
