Herod possibly forgets that the Dunker was programmed to roll the way the blades would turn you during a ditching. Unfortunately, the Sycamore blades went round the other way from most other aircraft of the day.
The sheer terror when they turned the lights out to simulate a night time ditching!!!
However, I am sad to relate that I was on my sea survival course at Mountbatten when we lost a Master Pilot in the water.
