Re JT #11 and #25
Knowledge, know how, and wisdom; much valued, difficult to acquire, often absent or mislaid in the modern world. Thank you.
We learn from mistakes - small one's. However, in a very safe industry, increasingly intolerant of mistakes, and with rare, unique events, learning tends to revert to theory and not practice (simulators are simulation, lacking 'surprise' and poorly represent the feel in event).
There is less requirement on memory, more on the written procedure and advice.

Unfortunately investigators, regulators, and ourselves increasingly mistake hindsight for the wisdom of foresight.
So let's keep to the simple things, follow the basic guidelines, and also be prepared, because when 'it' happens to you it will not be as per the book; not the engine, just the decision stop/go. The task is to manage the outcome.

Look at the day job. Contaminated operations involve new risks, in most areas mitigated, e.g. use max thrust. Yet these could introduce, new or overlooked problems; not the emotive Vmcg, but the simple 'off the side' during engine run up because the runway is more slippery than we are familiar with, higher thrust levels, wind.
