Washington D.C. - Today Masten Space Systems conducted a flight test of its unmanned Xaero from the Mojave Air & Space Port to a target altitude of one kilometer to test flight control at high ascent and descent rates. While the vehicle demonstrated better than expected performance through the test, unexpected instability developed during landing and the flight was terminated while the vehicle was well above ground level. The vehicle was destroyed on impact; no one was injured. The cause of the failure is under review, but a throttle valve malfunction is suspected.

CSF President Michael Lopez-Alegria stated, "Despite the loss of Xaero, the Masten team completed virtually all of their test objectives and collected invaluable data from the flight. More importantly, the personnel from Masten and from the Mojave Air & Space Port, as well as the hardware and software in the flight termination system, performed flawlessly. The vehicle impacted within the designated test area and no one was injured or endangered. It is the nature of the flight test business to occasionally experience anomalies; I'm confident that although Masten lost a vehicle, they gained important data that will be put to good use as they continue to develop their designs. I expect to see Masten in the skies again soon."
