HELP NEEDED--Cat in a tree--ideas?

Our neighbors work with the local, county SPCA. About a year ago she adopted two feral cats. They let them out during the day and keep them in at night (we have coyotes here in the mountains). When they went to get the cats in last night they couldn't find one. The lots where we live are heavily wooded and about 4 acres each. They finally found her about 40-45' up in a pine tree. We tried coaxing, food, cat nip, toys, etc. and even trying getting to her with a 24' ladder but the lower limbs of the pine are all dead and rotted. This morning the cat had moved about 20' feet further up. They called a tree service who climbed to within two feet and nearly had her but she got scared and went another 20' higher (all told about 75' feet high now). The tree service wasn't comfortable going any higher as they were worried about the "green" portion of the pine not supporting the climbers weight. Local ladder trucks w/ the fire department aren't an option and what we call "cherry pickers" (sometimes called bucket trucks) can't get that deep in the woods.

We're at our wits end trying to help our neighbors and Luna, their cat. With all the animals lovers on here we thought it was worth a shot to try crowd sourcing it. Any ideas, suggestions, etc. would be appreciated.
