So there's a reason pilots have a protocol when it comes to landing, and that reason is "Duh." Someone's got to make sure another plane isn't trying to land at the same time or that there's not a rave occurring on the runway. So when two Ryanair pilots came in for a landing in Spain and noticed that none of the strip's lights were on, they probably had a moment where they looked at each other and gave a collective "Oh shit." They had completely forgotten to tell the airport they were coming. It wasn't until they had safely landed and were taxiing to the gate that they figured out their mistake.
"Shouldn't there be a jet bridge here?"
"It's like 20 feet. Don't be a pussy."
To make matters even worse, the tower at the airport tried to contact the pilots to see where/who they were, but the pilots turned down the emergency radio frequency channel. The airline claimed this procedure was common among pilots to avoid "distractions." (You know, those annoying distractions that are broadcast on a fucking emergency channel.) To make this fail complete, air traffic controllers had forgotten to contact the plane prior to their landing as well. It's like everyone involved was Denzel Washington in Flight, but less competent and more coked up.
