At exactly midnight, while everyone in every Vegas casino is singing 'Auld Lang Syne' the tower is blown up and Vegas goes dark. The backup electrical systems open the cashier cages instead of powering the emergency lights. The inside men sneak into the cashier cages and collect the money. They dump the bags of loot into hotel's garbage bins, go back inside and mingle with the crowds. As soon as the lights come back on, the thieves stroll out of the casinos. A garbage truck driven by Josh picks up the bags and passes through the police blockade. It appears to have gone off without a hitch.
