On May 25, 1998, about 1150 eastern daylight time, a homebuilt Mohr Skybolt, N6JJ, registered to a private owner, crashed on landing at the Lakeland Airport, Lakeland, Florida. Visual meteorological conditions prevailed and no flight plan was filed. The private pilot reported no injuries. The airplane sustained substantial damage. The local personal flight originated from the same airport, at 1100. According to the pilot, he intended to stay in the local traffic pattern and perform some touch-and-go landings. He said he had enough fuel for an hour, but the pattern got busy so he was about ready to end the flight. He landed on runway 23. The airplane departed the runway to the left, went over a grassy area, crosses runway 9/27, broke off one of the main landing gear, a wing struck the ground, and the airplane ground looped. The pilot was issued an NTSB Form 6120.1/2 on May 27, 1998. Many attempts were made by the NTSB on the phone and in conversations with the pilot to help him complete the form. He always gave reasons why had not completed the form and always promised he would. As of December 17, 1998, the completed NTSB Form 6120.1/2, was never returned, and there are no written statements from the pilot on the events of the accident
