Like cambioso said, probably somebody who didn't have a clue where he/she was, but their GPS was on and following a GoTo somewhere so must have been ok.
I was accused by an R44 pilot once of illegal formation flying (once the CAA received the MOR) when i followed him to get the registration after he blatantly flew through our DZ with jumpers under canopies.
The sky is so full of incompetent cretins these days, it's every man for himself I'm afraid. On virtually every flight in GA land, I see examples of plain stupidity. Unfortunately, common sense and intelligence are not examined at any licence level.
