Oscarmike, with a Jodel you know at least that if the worst happened ......... it will float!
Unfortunately two Jodel's have ditched in the past on flights from the Isle of Man - one sadly fatal.. I can recall four ditchings (that is to say controlled landings on water rather than uncontrolled impacts) in the last 30 years but there may have been more. One of the Jodel's was flying the short 15nm crossing to Burrow Head but he still ended up in the water.
Never convince yourself it won't happen - take sensible precautions.
