OK- some published stuff-
Michael Alsbury, 39, was an experienced flier who co-piloted the same craft when it first broke the sound barrier last year. He worked for Scaled Composites — which built and operates SpaceShipTwo — for more than a decade, according to his biography.
Alsbury held the titles of project engineer and test pilot, and was also sitting in the co-pilot's seat when the craft was first dropped in 2010 from its carrier aircraft several miles above the Earth for an unpowered glide test. According to test logs, Alsbury flew primarily as the craft's co-pilot, logging at least seven trips from 2010 to early 2014.
Alsbury's official bio says he held a B.S. in Aeronautical Engineering from California Polytechnic State University-San Luis Obispo and was a member of the Society of Experimental Test Pilots and Society of Flight Test Engineers. The undated bio said he had 15 years and more than 1,800 hours of flight experience, and held his single and multiengine instrument commercial, glider commercial and single and multiengine instrument flight instructor certificates.
Peter Siebold obtained his pilot's license at age 16.
[4] Siebold has been a design engineer at Scaled Composites since 1996.
Siebold holds a degree in
aerospace engineering from
California Polytechnic University at San Luis Obispo, from 2001.

Siebold was responsible for the simulator, navigation system, and ground control system for the SpaceShipOne project at Scaled.
Although he was one of four qualified pilots for SpaceShipOne, Siebold did not pilot the craft during the flights later in 2004 to meet the requirements of the
Ansari X Prize.
[5] Although Siebold flew SpaceShipOne to an altitude of 32 km (just under 20 miles), he did not cross the 100 km
Kármán line -- the international standard for reaching space.
For his contribution to the SpaceShipOne project, Siebold, along with
Mike Melvill and
Brian Binnie, received the 2004
Iven C. Kincheloe Award presented by the
Society of Experimental Test Pilots.
Siebold became the Director of Flight Operations at Scaled.

He was the pilot who flew the
White Knight Two on its maiden flight on the 21st of December 2008.
[6] He won the Iven C. Kincheloe Award a second time in 2009, this time individually, for his work on the first WhiteKnightTwo,
VMS Eve, as chief test pilot.
