And talking about best methods of retardation on the landing run reminds me of the RAF flight safety magazine "Air Clues" describing an accident incident where a Vampire pilot ran out of brake pressure and looked like going off the end at speed. In his report he described whipping open his sliding canopy in an attempt to create more drag.
In reply, the editor of Air Clues one Wing Commander Spry (a wonderfully evocative name) commended the pilot on his theory but then nailed the pilot by saying that more drag than an open canopy could be gained by simply knotting the corners of the pilot's scarf and then holding it out in the breeze like a braking parachute...
