The Orbital Sciences (OSC) A-1 X-34 test vehicle completed its final captive test flight last month, under the belly of an OSC Lockheed TriStar, from the Dryden Research Centre in California.

The A-1 vehicle will be upgraded and used next year for 120km/h tow tests on a runway, and for further captive flights.

The second X-34 - the A-2 - will make the first powered flights, using a Fastrac engine, from Dryden, Holloman or the Kennedy Space Center, pending environmental impact studies.
