crash
Jesus Fucking Christ. When "crash" just doesn't mean the computer is going down. Remember that 3 hour delay at LAX (Los Angeles International Airport) a couple of weeks ago? It was because a Windows server crashed, leaving 800 planes stranded in mid-air, completely out of touch with the air traffic control system, and leading to at least 5 instances of near-collisions.
If you ever fly in and out of LAX, I would suggest writing to the FAA to fucking switch back to using a UNIX system. Those things can run forever without crashing, while a Windows computer is apparently supposed to crash every 49.7 days or so.
