Mighty Hunter, I was just referring to a common perception that anything without state-of-the-art avionics, and with engines which probably haven't burnt fuel in anger in years, is less safe than the latest airliners.
As to whether this perception is right or not - that's one I'll leave to the experts.
Does anyone think we mere pax should read anything into the fact that, on the Pprune listing "Passengers and SLF" is the lowest of the low?
