Human Factors; Procedure
I was taxiing to Runway 12 via taxiway alpha and witnessed a near midair collision. The runway in use at the time was Runway 12 as there was a [Cessna] 172 on final approach and another aircraft at the run up area near Runway 12. A Cessna 172 was on final approach for [Runway] 12 and a Stearnman was taking off on the opposite end of the runway (Runway 30). I witnessed the two aircraft flying right at each other and the Stearnman flew right over the Cessna 172 at approximately 200 feet and then banked to the right. There was an argument over Unicom that occurred between the Cessna pilot and Stearnman pilot. The Cessna pilot was an Instructor Pilot and basically told him the runway in use was 12. The Stearnman pilot was argumentative and suggested he is also an Instructor Pilot and that the pilot determines the runway in use at an uncontrolled airport.I am reporting this because of the safety implications. The Stearnman pilot was clearly in the wrong; but expressed that he was right over radio chatter. My goal here is to initiate the required actions to ensure this never happens again as I do not want to see someone get killed because of an unsafe pilot.
C172 pilot reported a NMAC; witnessing a Cessna landing on runway in use; while a Stearman took off opposite direction.
