And another.
ISTR once seeing a parking ticket issued to a Wessex, pinned up in the 18 Sqn crew room in Gutersloh (late 70s).
The story went that while on exercise on the Causses de Larzac, the aircraft had somehow managed to find itself recceing the noodie beaches found down on the nearby coast.
It being a hot day, the crew decided a dip in the Med was in order, so put the aircraft down on the side of the coastal road and went for a quick swim.
On their return, they noticed something under the windscreen wiper, which turned out to be a parking ticket issued by the local constabulary.
Vieux Guillaume must have had a chuckle as he found the Wessex illegally parked, written out the 'papillon', then climbed up to affix the notice in the traditional position.
He probably dined out on the tale for years afterwards.
