brain fade I assume by your comments that you're not a pilot? If you are, god help anyone who flies with you.
SOP's are there to be followed NOT ignored.
Both crew members are to blame here. The Captain for obvious reasons, and the FO for not filing an ASR and not entering anything in the tech log.
The FO should have reacted better in hindsight. Surely Boeing or the leasing company would have something to say if their aircraft was operated beyond it's limits?
The picture would be different if this aircraft had gone off the end of the runway........
