Reminds me of an article in RAF Air Clues light years ago. The pilot in a Vampire had brake pressure failure (they operated pneumatically)which he noticed on the pressure gauge while on downwind leg. In his accident report (he ran off the end of the runway)he stated that he wound open the canopy on touch-down to create more drag.
The Air Clues editor (a kindly old chap going by the name of Wing Commander Spry), couldn't resist a gentle dig at the pilot. He said that opening the canopy for drag was fine , but that more drag could be attained if the pilot had folded his handkerchief at four corners and hung it out of the cockpit like a braking parachute....
Nothing to do with Cessnas of course, but I liked the story.
