Re the Concorde, I have yet to read an authoritative detailed report. However, I think we would all agree that the crew was faced with one of those nightmarish horrors which we have all contemplated over a beer.
It is quite obvious that, whatever the crew did, the outcome was going to be unpleasant at best. In the event, the continued takeoff evidently led to a directional departure and subsequent uncontrolled impact with predictable results ...quite possibly this was one of those times when the after V1 RTO option may have been the better course. The remaining option, of course, was to throw the beast back onto the ground, off airport, when the control problems became manifest. I have no knowledge of the local topography so I can only speculate. I always recall the Sioux City DC10 accident ... it is quite amazing just what can be survivable.
It is very important to remember that the certification performance doesn't provide any guarantees at all.. only some reference data ... the pragmatist would likely take the risk averse position that the crew did their best within their training experiences with the information available in a very dynamically developing situation but it was just one of those days when taking a sickie would have been the better option ......
