If you were to blow by security, there is a very good chance they would close the terminal, and require everybody to leave the terminal and be rescreened once they have searched the terminal to make sure you did not leave anything hidden anywhere. It would not make for a pleasant experience for you or anybody else traveling.

There is probably no chance what so ever of you getting onto a plane that takes off without being screened, even if that means they need to take everybody off every plane there and rescreen them and their stuff.
