These guys found out the hard way with one guy jumping out at the wrong time with his parachute. It seemed the parachute got knocked by the blades from the heli. LOL. The heli video gets better when the guy actually lands on the burning building and some of them jump out. Everything seemed okay until the helicopter flipped off the building and the pilot ran after it. As he ran, the building gave up and collapsed killing everybody on that rooftop.
Jump to 1:20 in the video to watch for yourself!
