Treescapes were also issued to Canberra, V Force and FAA crews. For all except Canberra Nav/Observers the kit was in a canvas pouch worn on the chest beneath the LSJ. The Canberra Nav/Observers spent most of each flight in the prone Bomb Aimer's position in the nose of the aircraft. The extra pouch on the chest would have been a hazard while moving in or out of the nose and made it more difficult to use the Bomb Sight or Camera. It would also have been very uncomfortable lying for a couple of hours on a chunk of metal (the controller) whilst being pounded with the ever present low level turbulence.
The Treescape issued to the Canberra Nav/observers was in a polythene pouch carried in a flying suit leg pocket (how well that would have fared in an ejection is a matter of conjecture!).
The drill was to attach one end of the 200' length of paracord to a convenient branch,(if you could reach one) or to the parachute and harness which with luck would be firmly attached to the tree. Attach the controller to the lifting webs of the LSJ, drop the PSP, and after a quick prayer, release the parachute harness and gently lower yourself to the ground which would also hopefully be less than 200' from were you started!
I dont recall any being used in anger in 1963-1965.
