No survivors: Zombies attack RAF Lakenheath Published Oct. 22, 2012 By Senior Airman Morgan 48th Fighter Wing Public Affairs ROYAL AIR FORCE LAKENHEATH, England -- More than 100 base personnel volunteered to be undead during the Survival Challenge run hosted by Lib 5/6, RAF Lakenheath's E-5 and E-6 private organization Oct. 19, 2012. Runners were released in groups of 8 to 15 through a base-wide course filled with peril. Their objective was to finish the run with at least one of their three "lives" remaining. The zombies were classed by speed; "crawlers" were slow, "lurchers" were a medium speed and "the infected" were sprinters. The event mixed fun and fitness with the spirit of Halloween.
