I can't get the video to load, but assuming from the filename its the Intruder on the deck of a carrier... The story is that the guys helmet was sucked off and hit the blades first, causing everything to shutdown before his head actually hit
His Floater Vest got cought on a sensor in the intake (probablt T2/P2), there was still enough suction to pull off his cranial/ear defenders. This is what blew the engine. No one realized what had happened until he wriggles out of the intake. His injuries were a broken collar bone and bruises.
