I pulled onto Granbury; TX (GDJ) runway 14; stopped and set the directional gyro. Just as I started my takeoff roll I saw a plane shadow come by followed by a yellow or orange cub or Aeronca that flew over and landed in front of me and stayed on the entire length of the runway.   I was monitoring the radio and had announced my intentions. The only thing I heard was while I was taxiing a helicopter announced entering a left downwind. I was watching for him. The helicopter came over the runway low and slow about the time I reached the taxi end. I did not hear a transmission from the cub or aeronca and I did not see him when I scanned the approach. He could have made a left base (right traffic) or whatever but I did not see or hear him. He flew directly over me some 25 feet above.I reported this to the Airport Manager and another airport employee. The other employee said there had been a Chief or Champ landing there with no radios.
C-170 pilot reported another aircraft flew over him with about 25 feet of clearance when he was in position on the runway at GDJ; a non-tower airport. The other aircraft reportedly was not equipped with a radio.
