Meiringen Air Base, in Switzerland, has an unusual feature: two public roads that go straight over the runway. How do they keep it safe? And, as a side note, just how loud is it when you're standing next to a fighter jet? (Bonus things that didn't fit into the video: the aircraft aren't stored in hangars, but in caverns tunneled into the hillside! And if you want to get really close to the jets, there's a second, much narrower crossing over a taxiway to the caverns. They're not taking off at high speed there, though.)
