Having worked for a company that had flown a couple hundred thousand commercial R22 and R44 hours without a single loss of control accident like that which worries Lu and the FAA so much, I'd like to make an observation.
The key to safe flying in these machines is currency and respect.
We have also noted that new-hire pilots who are very low-time and were trained on machines like the Bell47 have a difficult time adjusting to the low inertia rotor. They retain habits that are very inapplicable to the new type and tend to be slow to pick up the new skills.
I can't imagine hopping into a machine for a couple hours every couple months and feeling safe, let alone owning a helicopter and renting it out to someone like this! Its a serious business.
