Maybe it was a lost spray plane, (don't laugh if you punch in the wrong start coordinates it can easily happen
) I just hope it wasn't pushing out an insecticide like Phosdrin or herbicide like the innocently named Sprayseed both of which in undiluted form are fatal if you are silly enough to drink some. I wonder what height it was flying.
The pilot was obviously looking for something to fly a pattern like that even though the lines were flown semi consecutively to avoid very sharp turns. The unanswered question is what were they looking for, realestate, drugs, cars, solarpanels, nude sunbakers, the mind boggles.
