I was the flight instructor on a training flight with a new student. We entered the traffic pattern at O61 with a left 45 entry for Runway 13. We had made a radio call on CTAF for the 45 and for downwind when the military trainer called that he was going to back taxi into position for 13 (no parallel taxiway available). We responded that we would extend the downwind leg to make space for him. We then made our radio calls for turning base and final. The trainer began his takeoff roll; and transmitted that he was departing 13; and would make a turn back over the airport (no indication of at what altitude). I transmitted that we were on short final. As we were in the flare on 13; the trainer made a very low altitude right 90 degree turn followed by a left 270 and lined up with the runway; descending quickly toward the runway that we had touched down on. Since he had had his landing gear up; and was using a smoke system; I was becoming sure that he was attempting a flyby (opposite direction). I transmitted that we were still on the runway. The trainer went directly over our aircraft at very high speed; clearing us by about 50 feet. The pilot apologized and said that he had not heard our transmissions. Another person at the airport indicated later that he had heard all of our radio calls; so the radio issue must have been with the other aircraft. There was no damage or incident.
An instructor on short final to O61 Runway 13 made the appropriate CTAF position calls but after touchdown were overflown by an opposite direction antique military trainer whose pilot stated he had not heard the previous calls before his takeoff.
