The terrorists shooting is worse than I'd anticipated.  He blows out the cabin, shooting a perfect circle in the fuselage.  I am sucked out at speeds approaching 342.6872mph, along with the rest of the contents of the aircraft, including a snack trolley.
Off the subject:  I have no idea whether or not cabins are pressurised at this altitude, but I can imagine it would be pretty hard to breathe at 25000ft.
