For anyone interested - helicoptor down near Hilo (ITO). Initial news was on this site -
Helicopter makes hard landing near Hilo Airport - Hawaii News Now - KGMB and KHNL and local media are saying it was an autorotation after engine failure. According to other media reports the pilot informed ATC that he had engine failure but the passengers have said he ran out of fuel. I'm not a pilot, just reporting this in case anyone is interested. There were no serious injuries.
