US withdraws all B-1 bombers from RAF Fairford after suspicious incident. The US has withdrawn all B-1 bombers from RAF Fairford amid an investigation into an alleged terror plot targeting the British base. Last Sunday, a farmer reported a group of men with several vans engaging in "suspicious" activity, prompting police to evacuate 85 homes. Five London-based Britons were arrested in connection with the incident and later released on bail.
