Well, cutting like that you bet it is. However if you have a look at RC1's video,
Horse chestnut felling you'll see many lifts performed with him nowhere in sight.
If you look at the underneath of the limb being cut in the picture above you'll notice some barber chairing occuring from the force the crane is exerting upwards ... I'd be hiding too and only be risking losing one arm in there not two if things went a bit crazy.

If the preparation cuts are made and the climber evacuates then wouldn't that have to be a superior method? Tearing and forcing is not the same as hinging and risks barber chairing. The method also may invite the climber to return to the action area to complete the cut if the crane doesn't forcibly tear it off.

Maybe so, but I would be embarrassed to start a
How to one hand a saw training program. I wont say you should do it, I'll even point out you do it and should not, and if you do it be mindful of it and make it the exception rather than rule ... complacency can bring surprising consequences. Also, we do a lot of palms, I have stood and watched many try to be efficient without one handing and cutting below shoulder/neck height ... using hand saws etc ... just doesn't work out. I can say every single person in 10 years who I have seen cut a palm down has one handed the saw ... there is not one exception. But we aren't discussing "
How to cut down a palm" here.

Sure, we can discuss why or why not, but there's little a how to guide offers when it is so prolific in errors.

Absolutely not. I challenge lots of things from developers to council to other arbo's whatever. I also see it as irresponsible to show this type of thing to noobs as a how to guide. Would you favour a newspaper that printed lies?
We all have the right to know best practice and frankly as professional arborists it's time to challenge the status quo. That chunking out method is seriously dangerous. I hired a climber once who did that to 6' sections of palm log, the whole thing was out of control ... logs landing in wrong spots and tumbling ... chains getting derailed on saws. One climber down the track slipped on his spurs in the middle of one of those push off positions and chainsawed his arm ... 33 stitches. That happens coz you have to lean forward and push and could kick out.
It is certainly not something I can add to the Tree Fact Factory on crane removals. It simply wont fly and no matter how many people say the earth is round they're wrong ... it's oblate spheroid.
