A great capture "eno"...
Many small towns and villages here have designated helicopter landing pads for military, police and medi-evac helicopters.
That is part of the town or village Emergency Measure Plan along with signs along the roadways designating Emergency Evacutation Routes.
I am surprised they have not done that where you are.
It would seem Great Britain has forgot the lessons learned from World War Two....which work for Peace Time Emergencies like Medi-Evacs, Forest Fires, Floods, Prison Breaks and any aid to Civilian Authorities...etc. etc...
Cheers...Happy Landings...Doug
