Brabazon regarding the hoist used in Stornoway I was one of the twin otter pilots based up in the fab Western Isles when the pan am airbus came in and the hoist we used then was a normal fork lift truck with a box attached to it for washing high up windows and it was probably the same they used for the 767.
p.s for the folks out there that think that the western Isles has very limited emergency equipment you really don,t know what your talking about. oh and they also have electricity !!!!
