a rarely seen video of a U.S. Navy SEAL extraction filmed from inside an MH-47 Chinook helicopter. The pilot has lowered the ramp, dipped the tail end into the water to partially flood the compartment, (a maneuver
that requires very Precise flying) and awaits the Navy SEAL's to board in their F-470 Zodiac.

Very few Pilots would attempt this, too easy to lose lift, and ditch the whole chopper.
