Arborist in a tree
Was looking to see how many departments ever had a drill on getting an arborist out of a tree. Im not saying the easy throw a ladder or the main to the guy and remove him. I am more going at the, you cant get a ladder to the vic, and the first branch/leader is 40 to 50 feet away. The other way I was thinking of it was same set up no ladders, and the vic had cut all the leads off the tree and was gaffed into the pole at the top. That last one just happend in Lower Makefield, PA. Vic at the top of the pole uncon and there was no close good over head. Any thoughts?

If there is still a strong top branch you can use a rope gun/rope sling shot to pull a rope over the branch then anchor it to the ground. Then someone would would ascend the rope with a mainline belay line a pickoff strap (or whatever you use to do a pickoff) and some stuff to make some change of directions. Once on top set up your change of directions, one around the branch and one around the tree and the branch in case the branch breaks. Run your mainline and belay through the COD's and anchor the lines to some anchors on the ground, set up the mainline for a lower. connect yourself into the newly set up lines, disconnect your self from the line you ascended. Then you would lower down to the pt do a pickoff and get lowered to the ground.
I'm not sure about the other situation, do you have any links to the story? Do you know what they did there?
In a pinch would it be possible to use a wrap 3 pull 2 around the top of the pole, would it pull enough friction to safely hold the load, obviously it's not ideal.

If the overhead branches are thin or gone and you can't reach him from the ground, then it's time to fly. Helicopter to the top of the tree and climb down instead. He can be removed either by lowing the old fashioned way or by way of the helicopter.
Or, find another arborist to get them. That is what was done in recently when a small plane ended up in the tree canopy outside KBDL. A tree company nearby came along, climbed right up, and got everyone down.Even the burger-flippers at McDonald's probably have some McWackers.

A wrap 3 pull 2 would most def have enough friction to hold without sliping. The only thing to watch for is the distance you will have between the top of the pole and the vic. Most likely in this situation the vic is going to be standing chest level or a little higher to the top of the pole. Reason being is that he/she will be spiked in with a lanyard/flip line around the pole. With the the one stated above he was just as I stated, plus knocked out due to the log he had cut came back at him striking him in the head ( that leads to are you going to secure the neck and spine aloft or on the ground?). This vic had no climbing line just gaffs and lanyard (very common). Not sure as how they went about preforming the rescue, I am working on finding out. I have done plenty of drills on this in the past and found the big thing is just being able to take the weight off the gaffs. There is a little bit of man handling to be done.
A good source of info to look up when you have time on the side of the setting lines from the ground is this link to youtube http://www.youtube.com/watch?v=KEKHGF_yGiw
This can also be done with a pulley attached to it. I had at one point figured out how to do it with a double pulley and have two lines set when all was said and done, forget how to now Dont forget, throwing a throw ball and cord into a tree is great, unless there is power lines there or cables in the tree. Even the best of guys get messed up by that

We did a drill very similar to this with a local tree service company's rescue instructors. Those guys were very knowledgeable. We made it simple.
Climb tree with spikes.
Attatch tether to victim
Get up above victim,( this was very relative, not a lot of room above,
had to take care when working around vic's gear).
Girth hitch a piece of webbing around very top (we had about 6"here)
Clip pulley and rope to webbing.attatch vic to this line. ground team lowers victim with this line
Also wrap a static line around top of tree with an eight on a bite with biner. clip rope through biner, making second girth hitch attatch your descender to this line
Carefully pull out vitims spikes, which lowers him into his flip line and your tether, and lower line ,then release flip line
rappel down with victim to help guide him
had to take care not to swing too far around on girth hitch so that it stayed tight and did not slip.
I know some of these methods violate some rope rules, but they work when other options may not

Rescue Response Gear did this video a year or so ago on removing an unconscious hunter from a tree stand w/o ladders used. Employing a belay line if you choose to go that route wouldn't be hard, they went with the single rope approach.
