President's Speed Challenge attempt. About 1 second into the flight at a speed of about 1360 MPH and altitude about 1500 feet, the airframe broke right above the motor. The nose cone fell free and was recovered with the electronics intact, the motor case and fin can came in ballistic and were found by the SLI team while they were searching for their rocket, and Dave N. found the shredded chute and the uppermost part of the airframe.
