Ashling I pasted the report on the 748 re-landing. This was not just a after V1stop but an after takeoff relanding on the remaining runway. Yes there was a severe fire with the wing alite but had the Captain followed normal procedures they would have not made a circuit back to a safe landing.
That is one of the extreme situations where the guy made the right choice.
I would not pitch my miserly 3600 hrs against some of you guys who have had many thousands of hours and diverse experience but maybe part of the problem here is that I fly as a Captain on Citations/Slowtations :-) Like the 748 they are both short field aircraft compared to most Heavies.
At Heathrow I know I could probably take the Citation off or land it three times so V1 will occur around a third down the runway. That itself may colour judgement which makes a stop situation not so clear cut as tons of heavy metal hitting 170kts before rotation.
