Way of thread, but someone mentioned STORNO's.
NUAS (Northumberland University Air Squadron) ((added for Wombat, oh, and welcome Wombat)) operated Bulldogs from Leeming most weekends.
This particular Sunday, a Bulldog started up when all of a sudden a crow decided to take a short cut through the propeller disc.
Not suprisingly, it came off second best. Remarkably it was neatly decapitated, the head landing about 20 feet from the aircraft and the the body, in one piece, (albeit minus a head), deposited itself by the front oleo leg. The aircraft shut down for checks but radioed ATC as to what had happened.
I went out from ATC, in the Trabant, to gather up and bag the remains.
When I got there, an audience of UAS studes had gathered and one brave soul had picked up the crow's head and was displaying it to his fellow studes with some bravado style comments.
As I opened the Trabant door, the STORNO made a squawking noise (as they did). The brave student leapt 3 feet into the air and the crow's head made it's final flight in the opposite direction.
Much laughter, with a red faced stude, ensued.
Sorry, Mods, about the thread drift but......STORNO brought it all back.
