VX275
I distinctly recall being on a Jeep Drop at Watchfield, there were two Jeeps in tandem underslung Hastings TG531 on 6th April 1955, the flight time from Lyneham to Watchfield and return was 1 hour and 15 minutes. My ATC 3822 mentions nothing more than this but I seem to recall 4 chutes deployed on each Jeep and what I recall that the aircraft appeared to 'lift' as the load was dropped. I was but 15 at the time
The set up was similar to this mock up at IWM Duxford Airspace hangar that I took a few months back
