RJ - you are definitely NL by another name. Once you start posting about old cars we will be certain!
Interesting that you chose the 2006 statistics. Wasn't that the year that the S76 out of Norwich lost a rotor blade? That being the first loss of life accident for some years. Even though you used that data to try to slew things (and as zalt points out, the FAA's idea of an accident is far removed from Europe's), in fact it makes the point that probably no, offshore helicopters will never become as safe as commercial airliners if only because there are so many more single point mechanical failures that can cause a catastrophic accident.
That doesn't mean we shouldn't try though! With the 7/7 items etc, safety can be raised but ultimately you are dealing with an intrinsically much more dangerous flying machine than an airliner.
