At about 11:40 Pacific time, a NASA Gates Learjet 24A was damaged during a hard landing at Southern California Logistics Airport. The two pilots and one passenger were not injured. The flight was conducting touch-and-goes. The pilot made the first touch-and-go. The copilot made the second touch-and-go. The copilot attempted the third touch-and-go but the airplane bounced twice and the right tip fuel tank dragged and separated from the airplane. The right main landing gear collapsed and the airplane skidded to a stop.
