Tree Fall (Pt. 2)

So, with two other trees under my belt, I called up my friend JB, who has performed well at the end of a rope as we sought to guide a tree down as it fell.
He was game for another tree-felling session, so we ventured over to B and S's house to drop a big old diseased pine tree that looked like it was on its last legs.  We looked things over.  It was a good day to work there partly because the tree would be falling into the street, but because the city was installing new water mains, the street was torn up and few people were using it.  The air was calm, no wind.  The construction crew was right up the block.
But we could see the drop wasn't going to be easy.
The tree stood next to the driveway in front of their house, its trunk split into three main sections that rose maybe 50 feet into the air.  Big.  Heavy.
And leaning just a bit toward the house, it seemed.
We examined the tree.
We walked around it, considering where it might fall.  We didn't want to hit the electrical can out front.  Or the fire hydrant.  Or the neighbor's tree across the street.
And we didn't want to hit the house.
So, we spent some time getting a rope into the tree as high as we could.  JB even climbed a ladder and threw the rope as high as could be.
We looked at the tree again.  There were some low branches on the house side we thought might be wise to eliminate, to avoid that dropping-on-the-house problem.  So we cut off several branches.
We tested the rope.
We warned the neighbor lady to get moving if she was going to keep her hair appointment.
I started my saw, adjusted my ear protectors, and I cut the notch.
Nice.  A good start.
Then I cut the back cut, deep into the tree, as JB put all his weight into the rope.
I could feel my saw binding in the cut.  I pulled my saw.  The tree stood, then leaned back toward the house onto the cut.  JB called, "I can't hold it!"
The tree stood.  JB pulled.  I ran into the street to join him, and we pulled on the rope, our desperation mounting.  It wasn't budging.  We were verging on panic, the huge tree all but cut in two, standing, barely, next to the house.  "I can't hang on," JB said.  I took the rope.
I'm not the best person to have in a panic like this.  I think my mind begins to skitter to a stop, the possibilities of what I might do going click click click like changing channels.  This one?  This one?  This one? This one?  Constantly stuck on not choosing.  JB does better.
One of us brought the pickup around as the other held the rope.  We tied it to the pickup.  It held tight, a taut line running from my pickup bumper to about halfway up the tree.  I could see the frayed spots on the rope, one knot where I had previously put my chainsaw through it.  Was there possibility of a breeze?
JB thought we could get someone from the construction crew to help.  I thought of other possibilities.  Crossed them off, thought of more.  All were pitiful.  And all would require that I admit that this tree fall was a disaster.
But JB decided to run up the street.  I talked to S on the driveway and couldn't help but make the dire situation clear.  Then JB came running back down the street.
