The sad fact is he almost made it to on Top....but did not.
If we work backwards....analyzing what actions he did take....and thinking about those he could have taken...and think about the effect the all had or could have had on the outcome of the climb to On Top....there might be some good Teaching Points to be had.....most of which are already known from other such tragedies.
Repeating them might help someone else down the road from making the same mistakes.
