Hornet,
the TCAS RA could have been over ridden if the 777 crew had the traffic in sight and was SURE that was the only traffic.
Your credibility is now zero.
After having read Robert's and others continued attempts to portray this as a non-event, I can now see why I don't like the US system or attitude. These two aircraft were seconds away from being wrecks on the 101, and all you can do is sledge the UA FO for not paying attention. Ridiculous.
