Send Clowns - I believe the Jet Ranger claim is that it is the safest single engined light aircraft in the world... at least that was the line I got from an Ozzy pilot working on The Great Ocean Road. But the exact definition of the rather loose term "safest" wasn't given!
Bladestrike - Cheers, but no mention at all makes me suspicious... Still, cars came out on top anyway.
Keep the replies coming - this is all very enlightening...
