Cactus,
UAL has some really weak pilots. They had a major screw up a few years ago on departure out of SFO in a 747-400. The F/O almost put it into the hill on departure when he couldn't handle an engine failure. If there is an error in this incident I would look to the UAL crew first, then the GA guy and the controller.
Who do you work for? Perhaps we can dredge up some dirt on it to question
your credibility.
It looks veyr much like this near miss had nothing to do with the UA crew. They were only airborne for a few seconds, on a collision course with a lighty that they knew nothing about effectively until the TCAS went off.
I suggest you stop trying to twist the event into something it is not.
