I was told a story of a similar phenomena which took place some years ago. It was a favourite story of the perpertrator, he told me about in person when he was my Station Commander.
This pilot from RAF Valley inadvertently drew a huge set of male genitalia over west Wales (a few miles straight and level, a 180 turn onto reciprocal track followed by a figure of eight)
It caused so much of a rumpus that a formation of four Hunters was scrambled to go up and cross it out!
