LONDON — British investigators Wednesday were trying to establish what caused a U.S. Air Force helicopter to crash in a bird sanctuary during a “low-level” training mission along the eastern coast of England in which four crewmembers died.
The helicopter was attached to the 48th Fighter Wing at the Royal Air Force base at Lakenheath, in Suffolk, which is also home to the 56th Rescue Squadron, the U.S. Air Force reported.
The USAF said in a brief statement that the crash occurred about 6 p.m. (1 p.m. ET), though Norfolk police reported it happened about 7 p.m. The local fire department said the first rescue unit arrived at 7:53 p.m.
