Royal Air Force firefighters from RAF Marham, Norfolk, kneel alongside U.S. Air Force firefighters as they put out flames in the live fire training house on RAF Mildenhall, England, April 5, 2019. The British fire crew visited the base to gain experience on the live fire trainer. With the arrival of the F-35 and the regeneration at RAF Marham, their training facilities are under renovation and the visit served to provide vital training for the RAF firefighters, and aid in continuing to build vital working relationships between RAF Mildenhall and neighboring fire departments.
