I was on the big clover intersection in LS that cuts right through the heart of LS, next to the tallest tower in LS. I had 4 stars on me, I was going south, I look to my left and I see a Beagle fly straight over, it actually maneuvered up and down to control it's altitude, but aren't planes in San Andreas programmed to sly straight?
Also, i was taking over the beach turf and had my Sniper zoomed in all the way, I see Ballas spawn and fly, disappear, and repeat the same process until I came close to them.
