At 5FTS Oakingtone we had to practice
At Oakington before the advent of Varsities we already had the experience of the ejector seat rig. Parachute drills we did at Ternhill where we practises pulling ourselves out of a Provost T1. The Meteor flight had to learn to bail out under the wing if in the front seat and over the wing if in the back.
We all had parachute handling so that we would cope on the ground. They would pick a breezy day and we would stand on the upwind end of the sports field with a parachute on and pull the rip cord.
There would be a short interlude where you failed miserably to control it before you were flat on your face being dragged across the field by the parachute with the instructor PTI running beside you shouting;
"Pull the lower cords and spill out the air."
Fat chance; the only relief was when the chute collapsed over a shed in the other corner.
