Hush House
SPANGDAHLEM AIR BASE, Germany -- Master Sgt. Christopher Montoya, 52nd Component Maintenance Squadron, checks out the new Program Logic Control system in Hush House three Sept. 21. One of the things the PLC controls is the amount of air intake allowed in the building during an engine run and can be customized depending on how much air a specific engine needs. The Air Force is standardizing all Hush Houses and all of them will be receiving the PLC system. (U.S. Air Force photo/Airman 1st Class Nathanael Callon)
