Such as:
”What could the 777 crew have possibly been thinking was their game plan, as they taxied to runway 31L? We don't know, and shouldn't speculate. Wrong taxiway, wrong routing, wrong runway, wrong direction, wrong signage, wrong clearance, no confirmation. This, in the face of having run performance numbers for a different runway (4L), accepted a clearance for 4L, received taxi directions for 4L, been given a hold short on the way to 4L at Kilo, and almost certaily having briefed the taxi to 4L. What could they have been thinking? I'm quite certain of what they were not thinking: they were not thinking they'd intentionally taxi somewhere they weren't cleared. They were not thinking they'd taxi to a wrong runway. They were not thinking they'd create a runway incursion.”
No speculation there!
