The Fistral deaths occured next door to the new SAR base and far, far closer to it than Culdrose or Chivenor ever were.
Camber is round the corner from Lydd.
I'd wager that part of the problem is the huge amount of publicity on TV given to SAR in recent years, making people feel safer, expecting that the minute they get out of their depth a man on a winch will appear out of the sky.
I once saw a road safety expert suggest that rather than seatbelts, air bags and ABS we'd be better off with a six inch spike on the boss of the steering wheel. You'd drive far more gently knowing you'd get stabbed in the chest if you stopped in a hurry
