A friend spoke to the operator. He was kind enough to give permission for the story to be told here.
it was a 23 ton crane at 60', good for 2,800 lbs, he told the bucket op he was good for 2,000. Tree had been brushed out already so this was the second pick, at about 11 AM. Outriggers were fully extended...
Crane op with 30 years experience says he had worked with this crew before and he would tell them what he was good for and rely on their expertise to judge the weight. He knows oak is 65 lbs/sq.ft., but does not have a log chart. He says they would always come in just below the number he gave so he trusted them.
Piece ended up weighing 4,000, so it was a significant miscalculation of the weight by the bucket op. Tree company may have been hurrying.
Boom grazed the bucket and flung the bucket operator out. Crane op was going over so he didn't see exactly what had happened to the bucket op. Groundie brought bucket over to try to get bucket op off the roof, but b. op claimed to have broken his ankle and crawled his way up to the peak of the roof to wait for rescue.
Seems to me that the crane could have been set up a little closer, but there were probably wires in the way... And certainly a bigger crane would have been the way to go... 2,000 lbs isn't much to work with on a stick that size.
