The one pilot who has been identified (assumed PM) was quite an accomplished pilot:
"If you have heard about the Challenger CL600 crash in Truckee this week, that was relocated SAN QB Bret Ebaugh (QB 39380). Many of you might remember Bret before he moved up to Lakeville, MN. He was Type Rated on Boeing 757/767, Bombardier CL604/605/650, CL65, Dornier 328, and Embraer 170/190 aircraft. He also acted as Director of Operations and Chief Pilot for California Pacific Airlines and was a Manager of Flight Standards, Check Airman and Aircrew Designated Examiner for PSA Airlines. He was involved with the Boy Scouts and the Commemorative Air Force, out at Gillespie."
