Over 40 years in the construction trades I was hyper-aware of how hard it was to get the (still too low IMHO) safety precautions put into place. Even many workers, back in the 60's and 70's, resisted the changes because you had to be real man (i.e. John Wayne or Clint Eastwood) to deserve to work on the innumerable buildings going up in NYC.
Electricians led the charge in NY thanks to Harry Van Arsdale, head of the Electricians Local 3, but lots of other trades soon joined in the effort.
If the worker was fifty floors about his assigned work area, and not harnessed up, the whole thing raises a bunch of questions. He may have been sent to work in that area or he may have just been taking a look at what it looks like from the top.
I did that myself when Tower A was finished at the WTC. It was an awe inspiring sight (and being that high scared the hell out of me).
I hope Turner Construction doesn't try to ruin this guy's reputation. That's not been my experience with them over the past decades but everything is run according to the bottom line these days so who can say.
I'm sorry about the loss of a brother Sparky, and wish his family well.
