An excavation team has arrived at the site of a fatal helicopter crash in Norfolk.
Four people were killed when the HH-60G Pave Hawk came down at a nature reserve in Cley next the Sea on Tuesday night.
Aerial footage shows the extent of the damage at the wreckage site, which the BBC's Simon Newton says "is the size of a football pitch".
