 Kubrick shot a scene in the Norfolk Broads where a Westland "Wessex"  helicopter (flown by a stunt pilot) was required to fly low down  along a canal (the area doubling for paddy fields) while someone  fired a heavy machine gun out of the doors. The scene was shot at  dawn and the local police were supposed to have warned fishermen but  there was a communications problem. The many fishermen were awoken  by a US helicopter apparently machine gunning their "positions". The  Wessex itself was subsequently damaged during filming when the tail  rotor got pushed into an obstacle while the copter was parked.
