I didn't know that Urie was the HAVE REGION guy.

David M. Urie founded Technology Advantage in 1995 to market
aerospace management consulting services to emerging air and
space hardware competitors around the Pacific Rim. He is the
Former Director of Lockheed Martin Skunk Works SSTO and X-33
RLV Advanced Technology Demonstration Programs both located
in Palmdale, CA.

Urie's work as the program manger for the previously
classified Have Region project demonstrated that rocket powered
single stage to orbit vehicle were technically feasible which
led to the Lockheed Martin SSTO design approach. This renewed
interest established the X-33 program for which Urie was the
program manger responsible for developing the VentureStar Single
Stage to Orbit/Reusable Launch Vehicle concept and the X-33
demonstrator design. Recently, NASA awarded the Advanced
Technology Demonstration Program to Lockheed Martin who will
design, fabricate and fly an X vehicle to demonstrate the SSTO
technology and design approach in flight. Urie's technical and
program leadership created this success.
