Wild....I would rate that account as being just about perfect and I would not have done much different probably. The one thing I do to prevent such a situation as that is by eating lots of Cheeseburgers and Fries (Giant sized),so I will not fit into the door of a Robinson product.
Real EOL's are just a tad different aren't they?
Some quick thinking about the door....that was part of my standard brief to a co-pilot. It is much easier to get out than waiting until the cabin fills up with water then trying to open the door or jettison it.
There are some that cling to dogma, SOP, Checklists, et al....that will try to tell you all about the dangers of the door going through the tail rotor. My view is at that point in time....in the flare....that is the least of your concerns.
If you were facing the beach and down wind...and got much closer to terra firma both in depth and distance....it makes swimming much easier than out in the deep water.
