At 08:30 central time, a Curtis Travel Air 4000 vintage biplane was damaged during its takeoff roll from a private grass airstrip. The three people aboard were not injured. The pilot raised the tail at about 50 to 60 knots, the right main landing gear hit a bump, and the airplane became airborne and banked left. The pilot over-corrected to the right and the right wingtip hit the ground. The airplane then went through several fences.
