Pinkman:
We have a pax witness that says they were on as they disembarked
I just have to clarify one point: as stated earlier this observation was about 50 minutes after the incident, and taxiway lightning might have changed after the incident or because of the incident. We could all clearly see what happened without even knowing the taxiway layout when we got off the plane. The green centreline observation was made by a fellow passenger who were on the right side of the bus, and in retrospect, he could have just talked about the normal taxiway outer lights that curved to the left. This was my assumption when I saw the curve had green lights and not my direct observation. Sorry, not my intention to mislead anyone but just want to point this possibility out.
