We had good fun covering how aviation celebrated April Fools' and thought we were done, but this last prank was too good to pass up.
A pilot with a North American carrier says on Twitter that he sent this message below to his airline via ACARS (along with a note saying "Happy April First").
He also says, "I told all my passengers today we were going supersonic. I said it was only allowed on April first. I think most of 'em believed it."
