The old series 3 were rigged for roll out drops in the early years before the 463L pallet. The rover had the canopy removed and the chutes were in the back. Rover went out backwards. Vehicle was driven in and lashed down to the floor and at drop time it was man powered out with a bit of help from the pilot pulling the nose up. That was all before my time. I had the joy of rigging the series 3 with trailer and load onto a 347 L pallet in the tried and true methods but when we changed to the 110 it did not fly like the series 3 and we lost a few trying out different rigging methods. Back then we used mostly British style equipment with American compatible rigging methods.
