Human Factors
A BE33 had just landed on Runway XX when a PA18 Super Cub rolled onto final. Myself; along with two other pilot-rated observers; watched the BE33 (we were friends with the pilots and passengers on that plane) make a 180 on the runway to taxi back to the only exit from the runway. It quickly became clear that the PA18 did not have room to land safely; however; instead of a normal go-around the pilot appeared to buzz the BE33 by approx. 20-40ft. Once passed the BE33; the PA18 made an aggressive 180 degree turn and proceeded to land on Runway XY while the BE33 was still occupying the runway and taxiing back to the only exit from the runway. The PA18 landed and taxied to a hangar while the BE33 eventually cleared the runway and parked on the ramp with the pilot noting the incident. The incident was a clear runway incursion and not safe at all. While we did not make an attempt to contact the pilot (we were preparing to leave the area and return to our home airport); we agreed it was an unsafe maneuver. The PA18 did not make any calls on CTAF at any time while both my plane and the BE33 made calls for each leg of the pattern.
Third party observer reported a BE-33 pilot experienced a Critical Ground Event during landing rollout with a 'NORDO' PA-18 landing with the BE-33 still on runway.
