First Sortie
F-15 Eagle crew chiefs from the 48th Aircraft Maintenance squadron wait as a pair of F-15s warm up before takeoff, April 11, 2010. The crew chiefs and the aircraft will be operating out of RAF Mildenhall, England, for the next month, allowing the 48th Civil Engineering Squadron an opportunity to repair the runway at RAF Lakenheath.
