Thousands of people at London's Stansted airport were screwed up because some people deplaning from a Ryanair flight from Lisbon entered the terminal through the wrong door, breaking security protoccol and forcing the airport to re-screen everyone.
Who left the door open? I'm confused, as usually there are these things called "jetways," but I don't know Stansted airport and it was a Ryanair flight, so that's the equivalent of airborne steerage, and likely using a little-used gate or parking area because it's cheaper.
