When everything goes wrong!!!!!
A friend of mine sent me a miniature movie. It shows a CH-46 coming in very fast to a landing on the deck of a ship (Perhaps an LHA). He approaches the deck at an angle instead of coming to a hover in line with the ships centerline and then moving sideways keeping in line with the ships centerline. His nose gear hit hard and either he bounced or he pulled collective and tried to align with the centerline of his parking space.
In the process he came to a hover with half of his discs over the flight deck and half over the water. As a result he rolled to the left and fell over backwards into the water hitting upside down. It ended there with two high-speed boats heading for the impact point. I have no idea if there was any loss of life. I’m sorry I do not have the URL.
