DC-X FLIGHT TESTING HALTED DUE TO EXHAUSTION OF FUNDS

 LAS CRUCES, N.M., Oct. 25 /PRNewswire/ -- The Ballistic Missile Defense Organization has notified McDonnell Douglas that funding for the DC-X single-stage rocket technology program has been exhausted. Flight testing has been halted pending future funds.
 In the past two and a half months, the DC-X has completed three successful suborbital flights designed to demonstrate vertical takeoff and landing, subsonic maneuverability, airplane-like supportability and maintainability, and rapid prototyping development.
 Prior to the flight tests, the DC-X successfully completed nine static firings and two preflight readiness static tests.
 Each time the DC-X has been tested its flight envelope has expanded to subject the vehicle to increasingly higher altitudes, velocities, dynamic pressures, angles of attack and flight durations. The DC-X is the first vehicle to land vertically on earth.
 Last Thursday a flight attempt was scrubbed following vehicle shutdown on the pad. At 1.5 seconds into the engine start sequence, the vehicle on-board monitoring system detected out of tolerance parameters and immediately commanded the vehicle to shut down.
 The DC-X flight crew plans to continue to investigate the shutdown, determine required corrective actions, and maintain the vehicle and ground support systems in a readiness state, preserving the option to resume flight testing at a later date, if funding is made available.
