I was going to say that in offshore safety, almost everything is interrelated. You have the speed of response, because people don't live indefinitely long in our bitterly cold waters and high seas, even in the suits they have on. The other important thing is training for the people who are the passengers in the helicopter, training and knowledge about what to do if you have to ditch. A crash is a different thing, but if you have to ditch and you don't know what you have to do to save your life and get out of the helicopter.... They overturn because all the weight is in the top--the two engines, the gearbox, and the rotors--and almost always, especially in high seas, they tip over. You are then submerged. You have to be able to knock out the window, fix your disorientation, keep your head, and keep your wits about you. You have to be trained to do that, because an untrained person, in my view, would have very little chance of survival.
Those are some of the interrelated things. I won't take up any more time, but I would be happy to answer any questions provided they don't get outside the terms of my study.
