The hole in the hedge at the end of the Welshpool runway was caused by a number of overruns over the years. Most notably one where a student on early solo floated a bit and in panic stamped down very hard on the rudder pedals - imitating how one would press down on a car brake. Obviously to no effect - he trundled into the hedge at the end, throttle at idle at about 20kts. An ingrained motor response took over with the adrenalin and he simply never applied the brakes and froze.
In the second notable hedge trimming incident an instructor on a touch and go with a student suffered an engine failure on applying power. For the sake of another 3m he would have stopped before the hedge... well handled though.
Such legendary tales of instructors forgetting approach speeds should be treated with a bag of salt. How could you? You have to have a checkride + all the aircraft have the colour coded ASI's + all your small Pipers and Cessnas approach at 65kts ish.
Cheers
