The assumption always seems to be, from the usual subjects, that the crew were unprofessional dickheads who stuffed up and that they would never make a mistake like that.
Surely a more constructive approach would be to assume that the crew were highly experienced, professional and doing their utmost to get things right and have an uneventful day at the office. That then begs the question what would cause such a crew to end up in such a situation? Then we can ask of ourselves ...If it can happen to them how can I make sure it doesn't happen to me?
That way we learn about the dynamics of the incident what led up to it etc. Human factors, remember that? Or was it just an exam to be completed and forgotten about.
Until we know ALL of the FACTS, not just what we can observe from the photograph or by taxying past, then we are just speculating.
