Smudge,
One particular 'problem child' was the RIB (rigid inflatable boat) as used by the SBS and others. It seemed that every drop would produce a new incident. Perhaps we have someone around who could recount the tale of the Maggie Maldrop' !
This is the RIB as I always seem to remember it ! It should of course be descending gently in the horizontal plane not performing 'Stuka arrival one !
