So you’re flying your airplane late at night and approach an obscure airport. You try to radio the tower, but there’s no response. The tower is unmanned. Not altogether unusual… pilots are able to land at uncontrolled airports, using the radio to inform one another of their progress if there’s more than one airplane about.
Oh, did I say obscure airport? Well, there’s the problem. The airport where this happened last night wasn’t some municipal airfield in Wyoming or the Yukon. It was Reagan National Airport, in Washington, D. C.
Reportedly, the lone controller in the airport’s control tower either managed to lock himself out or fell asleep.
