smudge,
we had lots of problems with the liferaft hatches. The main problem was that our MS26 was larger than the USAF equivalent. I seem to recall one coming out in flight. The problem was exacerbated when the MS 33 was shoehorned into the the MS 26 receptacles. I attended two demos of the MS33 being launched from the wing of a Mk 3 and both times it just lay on the wing belching like a beached whale. Thank god we never had to attempt to launch it for real.
