At the beginning of the movie you see two C-130 Hercules (0:00:41) with there engines on. For a better view of them try frame (0:01:03). Then when Capt McCoy runs back to the burning helicopter to save his friend stop the dvd at (0:01:43) and you'll see the C-130 Hercule with it's engines turned off. Surely doesn't make for a speedy get away.
