Get pizza delivered when you're stuck, that is.
Passengers on a New York-to-Washington train were stuck in Delaware when the train quit working and apparently had little or no food and water for those on board. So some ingenious travelers ordered pizza from a delivery service in a nearby town, and the veteran delivery driver navigated the terrain to deliver the long-awaited pies.
Well, I suppose you might be able to call for pizza to be delivered if the plane is stuck on the tarmac or something, but airlines don't open the doors once the plan is away from the terminal. And United jets probably have .50 mm cannon turrets on the fuselage to nail Mr. Domino's before he gets too close.
On the other hand, when a train quits working it doesn't fall out of the sky. So maybe it's a wash.
