fjord, I gotta admit I'm still trying to figure out your motives. In any case, Wendell said there are studies that show that seatbelts and airbags can do more damage than good and he's right:

http://www.scienceservingsociety.com/ts/text/ch12.htm, (broken link removed to http://www.newsinferno.com/archives/18633). And those were Googled in 10 seconds.
But, this thread and its responses are more about the point (Wendell also said to use seatbelts, etc.) that safety features are imperfect and shouldn't be relied on. I'll take a sober man using a saw without a chainbreak over my drunk neighbor using a C-Q Stihl!

Sorry boys and girls, those are articles
about studies, not studies themselves, some with sources of real research. Interesting reading IF one seriously reads. Read carefully with some intelligence. Don't skim just to make your point.
Those sites ALL emphasize that the airbags AND full belts save lives. There are costs and situations where they MAY not be COMPLETELY effective. Nothing is. NHTSA and the insurance group do controlled research. Common knowledge for any gear. Nowhere do any of those links state that "airbags are unsafe", or that belts "cause more injuries" than airbagless or seatbeltless. READ. READ.
Now back to why you boys are so incensed by information for most who want to know how to use a chainsaw effectively and safely. Go to your corner....now.
WenDell: where the H do you have a 70" DBH Maple ? Dreams ? Want a 70" bar for this ? If you really want to know how to fell a world record holder specimen like that ( not in Wisconsin ), ask.
I can only tell you how we would drop a large DBH hardwood with a bar that is say 1/3 the thickness of the trunk. It's done all the time in normal felling and tree work. No logger, arborist, cutter runs around with anything like a 40" bar for normal work. 36" at most in the east and midwest.
Really want to know the technique ? Or, are you looking for more parody, juvenille ridicule and jollies ? Truth WenDell and Jay and Thinx. Truth. Don't just get ragey here on me.
So, ask in a way that may give you some new information. The technique for felling a large DBH tree with a short bar is simple, time consuming, safe with some easily learned skill.
P.S. "DBH" ---look it up.
