As an Air Signaller destined for Valettas in 1952 I attended a course at RAF Abingdon where I did the Forward/back/left/right roll training followed by zooming down in para harness from a tower to practice the technique. We graduated to a balloon jump where we volunteered the smallest of our four pupils to go first; we could hardly refuse thereafter. This gave us the certification as Despatcher, which was followed by a refresher course at MELF Ferry Point in the Canal Zone in 1954, courtesy of 16th Independent Para Bde group.
