Jake Busey played Jacob the religious nutter who does the suicide bombing. Just to mention again, Biscuit missed out the most crucial part in that, Joe's bomb at first fails to detonate as the trigger button becomes stuck, prompting Drumlin to scream for security as he chases's Joseph down a gangway construction, before one of the security tackles Joe. When we last see Drumlin, he is struggling with Joesph over the detonator, moments before Joe tears Dave's grip away from his detonator, pushes down hard on the button. Overhead cameras show staff members being enveloped in the flames (some pointlessly trying to extinguish the flames), moments before the camera's die.
