Other U.S.-supported facilities in Britain also tightened security, with RAF Lakenheath and possibly RAF Mildenhall moving to FPCON Charlie, the most stringent posture seen at these sites in 8 months. These measures include road closures implemented by local police and the denial of airspace transit to an East Anglian Air Ambulance flight. A USAF spokesperson stated the 501st Combat Support Wing remains vigilant but declined to discuss specific security measures for operational reasons.
