I rebuilt a 152 that had been flipped, we had to buy a backend off one in the USA, then join them together just aft of the windscreen. Pilot (French) was going to Paris but bad weather forced him to divert to Le Touquet airfield, imagine his surprise when out of fuel and with the weather clear he found himself over Kent, he put it down perfectly in a ploughed field in line with the furrows. Unable to fly out the USAF offered a CH53 to lift it, resulting in it upside down with the backend destroyed and the engine shock loaded.
The other was on the OCU when we took a Puma crew down to Fleetlands in a Chinook to collect a repaired Puma, hovering into the place next to the Puma it’s rotor blades did some pretty impressive movement resulting in us departing while they dragged it back in the shed to start again.
