Flying the barber pole
More of a pet peeve. My USAFR brethren who find themselves with extra gas coming back from a Europe TDY and decide to fly the barber pole for 7 hours on the NATS because nobody is stopping them. Dude, you’re saving like 15 minutes and burning 12,000 extra pounds of gas. You’re not maverick, it’s bad for the environment, and guess who’s paying for it? YOUR tax dollars.
