Playing on their computers is one thing. Ignoring air traffic control and being completely out of communications is a totally different thing. WHAT IS WRONG WITH THESE MEN? How could they have put 144 lives at stake for a "software lesson" at 30+ thousand feet? SHAME ON THEM. Even if you buy their story (I sure don't), it's ridiculous! Puh-lease. They should never be allowed to fly commercially AGAIN. Ever.
