MD-500E G-JIVE. The unfortunate was Roger Feather. Landed in a field at Nelson, Lancs. According to local news report, his "co-pilot" got out and accidently banged his head on the heli. Roger went to help him, and a sailing blade smacked him on the head, giving him a depressed fracture of the skull. Reported as "seriously ill".
(I know this machine, and unless it is a very recent addition, it is not fitted with a rotor brake)
I'm sure all our thoughts are with Roger and his family for a happy ending to this unfortunate incident.
