Senior Airman Michael Musgrove, a jet engine mechanic with the 493rd Aircraft Maintenance Unit, turns the shaft of an F-15 engine April 23 so his coworker can use a bore scope to look for any volcanic ash damage within the engine at RAF Lakenheath, England. Eight F-15s returned from Leeuwarden Air Base, the Netherlands, after participating in FRISIAN FLAG 2010. The aircraft underwent the bore scope inspection as a precaution to make sure they didn't take any damage from volcanic ash they may have encountered on their return home.

Tech. Sgt. Willie Mitchell, a jet engine mechanic with the 493rd Aircraft Maintenance Unit, watches a camera monitor while he “bore scopes” an F-15 engine April 23 at RAF Lakenheath, England. The bore scope is a small camera system that enables Sergeant Mitchell to inspect the rotors while his coworker slowly turns the engine shaft. (U.S. Air Force photo by Tech. Sgt. Nathan Gallahan)
