Veterans of the X-15 flight research program, most of them now retired, reunited at Dryden on the 40th anniversary of the last X-15 flight on Oct. 24, 1968 for a historical colloquium on the X-15 by noted aerospace historian and author Dennis Jenkins on Oct. 24, 2008. Gathered in front of the replica of X-15 #3 the were (from left) Johnny Armstrong, Betty Love, Paul Reukauf, Bob Hoey, Dave Stoddard, Dean Webb, Vince Capasso, Bill Dana (who flew the last flight), John McTigue and T.D. Barnes. Jenkins, the author of "X-15: Extending the Frontiers of Flight," maintained during his presentation that despite setbacks, the X-15 program became the most successful of all the X-plane research programs due to the can-do, fix-the-problem and go-fly-again attitude of the X-15's cadre of engineers and technicians.
