"And of course there are a couple of other points to consider - for
example the fact that the engine finally seized up just when he
started his turn to final. If it had delivered power for another four,
five seconds, he would have made it into the field."

Andreas, you cannot have it both ways, if indeed the engine delivered power for extra four or five seconds AND he turned early, than he would landed without an issue. Instead his plan, up to the time when he straightened to land, was to cross a busy highway twice. Cannot see that as the best decision.
