Similar tale
Sorry for the thread slippage, but similar incident without the tragic ending:
In a previous incarnation as a Navy Sea King Pilot, I remember a training incident whilst working with some SBS (Special forces). They were practising rapid rope deployment from our helicopter to the top of an artificial ski slope (simulating the bridge wing of a ship). We came in at speed then did a fast stop, the crewman would deploy the rope and the grunts would eagerly grab said rope and abseil / slide down the 40' to the ground. Fly away and pick up the next stick, simple.
On a subsequent approach just as the crewman was kicking the tail end of the rope out of the door, we had a tip strike on a floodlight pole, changing the game plan suddenly to getting away from the ski slope and getting the helicopter safely back on the ground. Despite the vibration, or maybe because of it, The grunts were so geared up to jump out of the door, the crewman nearly got taken with them as he stood in the doorway trying to stop them! Was everyone in the back safely strapped in for that landing? I think not, but nothing broken or even bruised except the pilots ego.
Easy done and the crewman in the back has a very difficult job looking out for everyone on board as well as looking out. With two doors ... Impossible.
