Not making any comment on the accident. But it does seem mathematically implausible for two Enstroms to be the same accident. In 20yrs of flying helicopters, the only Enstrom I’ve encountered was one on a static display at an air show. I’ve never encountered one on a ramp or in flight. It’s like seeing a crash between two hot pink Rolls Royces.
Results would likely have been the same irrespective of make of helicopter.
I learned to fly on an Enstrom. Nothing wrong with them.
