when it crosses the boundry, even if its in the air
A ball is considered dead when it goes out of bounds or is fumbled.
In American Football, if a player has one foot out of bounds when he catches the football, he is out of bounds. If he has is in bounds when he catches the football then he caught it and it is a completed catch. If the player goes out of bounds and comes back in bounds and catches the football it is still an incomplete pass. However, if he was knocked out of bounds or if the ball was tipped, it may be a completed pass. The rules keep changing at all levels of the game.
