Gulfstream Aerospace Gulfstream 3 (NASA502)

This Gulfstream III is a USAF C-20A, s/n 83-0502, msn 389 and assigned to NASA in 2002, according to Joe Baugher's information. Three of these commercial Gulfstream III aircraft were procured as C-20A types for presidential executive transport support. This one appears to have the "hushkits" retrofitted.
