non q question, but i thought i'd take advantage of specialist knowledge here on something that's puzzled me for years
happened back in the 90s in canada. living on an acreage, had just driven up to garage and saw small dark chopper flying quite low, maybe 8 to 10 feet up. it seemed to barely fly higher than the young apple tree it flew over. was approx 50 to 60 feet distant from garage. seemed as though the back door was open and someone crouching in the opening. chopper flew on, which took it out of view behind garage and house. raced around end of garage to regain view (so, a few seconds) but chopper was not to be seen, though still audible. landscape was such that if it had landed, it would be in view, but it wasn't. looked higher, no chopper. went back to front of house, still heard it but couldn't see it at any elevation. sound of chopper finally faded away but was never again in view.
there had been an armed bank robbery in a nearby town earlier that day with suspects fleeing. when i first saw the chopper i thought maybe they were doing a ground search. it was all a little spoopy. has anyone had similar experience of very low flying craft just disappearing from view?
oh, the next day in a different nearby town, i saw 4 dark green or black copters flying overhead in a diamond formation. would really appreciate anons' thoughts on this. no alcohol or other recreational substances were involved, kek.
