LCG comes together to face Challenge
VANDENBERG AIR FORCE BASE, Calif. -- 1st Lt. Michael Hoadley, a flight vehicle engineer with the 4th Space Launch Squadron, and Capt. A.J. Ashby, 4th SLS flight commander, go through terminal count down and procedures during a Guardian Challenge launch rehearsal on March 28. The GC trainers provide a series of anomalous conditions. This provides the GC team with familiarity of the launch count down manual and trains them on some of the day-of-launch systems that can become problems or barriers in achieving a successful mission launch.
