Four crew have been killed after a U.S. military helicopter crash on a coastal nature reserve in north Norfolk last night.
The aircraft, a Pave Hawk from the American airforce base at RAF Lakenheath, Suffolk, was out on a routine low-level flying exercise when it fell from the sky.
Residents of Cley-next-the-Sea heard a 'heavy and very unusual' sound overhead as the helicopter - which specialises in recovering troops from war zones - plummeted into flooded marshland.
The modified version of the U.S. Army's Black Hawk crashed just after 7pm close to the shoreline.
Police confirmed the chopper was carrying live ammunition at the time of the crash, and have set up a 400 metre cordon around the site to protect the public.
No adverse weather was reported leading to speculation that a bird strike might have caused the accident.
