A quick check on the NTSB site shows eight more accidents between 1/1/1998
and present date. Three of them were fatal. Four in 1998, two in 2000, two
in 2002, and _nothing_ since then, thank goodness.


A more detailed check shows 16 Mini-500 accidents between 1/1/1998 and
12/31/2000. Same period saw 28 Rotorway accidents.

Between 2002 and 2005, four Mini-500s, 29 Rotorways.

I'd almost credit those numbers to the difference in rotor inertia.

The Rotorway has a very light (relatively) rotor system with
correspondingly lower rotor inertia.

Big difference between 1-2 seconds to dump the collective vs 4-5.


Maintain thy rotor RPM lest the Earth rise up and smite thee...
