So walk me through the thought processes and the timing of the processes through which you'd obtain and consider, for example, the NOTAMs for the destinations you hadn't planned to use, while flying a damaged aircraft of unverified endurance that was short on endurance during taxi before take-off. Or do you subscribe to the 'as soon as I declare a MAYDAY the closest available length of sufficiently long piece of tarmac will be safer than any other option' theory?
