Clipboard stated (Re: 407 tailbooms)
"the occupants would have been statistics" . I suggest that you read the whole thread, I recall that a reliable source posted that there have been NO fatalities related to the tailboom issues with 407's. You mention that this pilot in question is a true professional ( I believe you), so I'm sure that he would react with his experience and manage a tailboom loss ...as the other pilots encountering it have done.
Personally, my tail boom has not fallen off yet, (my mechs have found a crack once) and I like the aircraft, so rather than whining about it, perhaps you should buy a superior EC product...they NEVER have problems I've heard ?? or perhaps ask the ENG pilot in NYC last week for his opinion
