During GW1 had many happy occasions stuffing stuff into the back of the Belslow. Came in alternately with the 'Guppy', a cavernous but utterly utterly useless aircraft. The Guppy always 'weighted' out way before bulkout!! Not a lot of use when you are loading pallet of Challenger armour!!
Last load that I saw going in the back of a Belsow was an 'Aardvark' mine clearance vehicle....a really serious piece of kit!!
