For $diety's sake, why do we need so much nitpicking.
The PF realised that something was wrong. He had plenty of room to stop.
He aborted and stopped safely. Well done that man.
Having been in a similar situation, albeit in a Twotter with more than plenty of room, I can assure you that it is not a nice experience. There will be a crease in the seat and a change of underwear may have been required.
Fast reactions combined with familiarity with both the aircraft and the field all contributed to a safe outcome. Would the aircraft have been safe to fly if he had continued ?, on balance it probably would, but he had no way of knowing that in the available decision time.
In other circumstances the outcome could have been very different but IN THIS CASE experience and fast reactions saved the day.
