Narrative:

In pattern downwind to land runway 9 at 3HA with another aircraft behind us. Runway was on our left with planes taking off. Another plane from right of us tried to enter pattern but we were there. Evasive action by him occurred and he came around and landed. #3 or #4 plane was on blind side and low until it was too late. Couldn't slow up any more so I stayed on course. Must have been 8-10 planes in area at time. A lot of talking, etc.
