To the idiot in the red and black 172N @ W00 at 9:20 am, what the hell was with that 45 degree dive from downwind to final for 18? You dove about 500 down and landed with an airplane still on roll out! The second time when I was taking off you didn't make any calls and dove yet again from TPA on downwind to final. You landed behind me and somehow cut me off on downwind. I'd like to know your name,address, and pilot #. If you read this, you ****ed off and endangered the other four planes in the pattern along with the people on the ground. No calls or anything! You sure did go around and haul a** out of Freeway when you were asked to identify yourself,so please identify yourself Two Eight Kilo!!!
