Sorry about having to bump into the thread here, but noticed a news article this afternoon which, to my merely SLF/attorney knowledge, seems quite pertinent.
Forbes reporting that the 106 FO, on first flight on 777 type (after experience on 737 and type training), was busy with new procedures, including making a p.a. announcement about imminent departure (article says "takeoff", but departure is the correct term, isn't it?). Article refers to input from an unnamed AA source; quoting, "she had just read the 35-page bulletin that changes procedures." Some content too about whether the changes in procedures were quite alright or not; per article, Allied Pilots Ass'n had initiated an "appeal" of their implementation.
Article notes also there was a third pilot on the 106 flight deck; that neither the PIC nor 3rd aviator saw the "stop bar lights on the runway"; and that AA 106 had just switched from company frequency to Tower frequency. AA 106 did not know the seriousness of the incursion until they arrived in London, per Forbes article. "Delta was cleared for takeoff before they switched over" to the tower frequency, the article quotes the source as saying.
An aviator active on Twitter, Kelly Lepley, posted the Forbes article. The American source it claims to rely on is identified as a "pilot" but not otherwise. [@kclepley - iirc, a UPS 747 captain]
Apologies twice for barging in on the aviator discussion.
