Day 194/23. Do aliens use propellers?

A hunt in Hampshire for crop circles today.... It's that time of year, just before harvest, when the 'aliens' visit to leave us these mysterious shapes in the fields. Much to the anger of the farmers.
We found two today. And in one the 'aliens' clearly know of and use propellers.
Or was it the chaps from the local pub after a few beers?
