Not directly pertinent to the present discussion but an interesting observation -
In the early days of CRM work, my airline was a main player in Oz. One of the emergency refresher school exercises for a while involved role play with two people out of each other's sight co-operatively trying to achieve a goal involving difficult communication against the clock. A typical exercise was for one to communicate the arrangement of a set of coloured blocks with a goal that the other should rearrange his/her set to match.
I found it interesting in the extreme that, nearly to a (wo)man, the aircrew folk played it down to the wire. Conversely, the non-aircrew folk tended to "throw in the towel" when it became evident that the clock was likely to win .. think I would rather the former fighting attitude in the cockpit with an unusual, potentially catastrophic failure .. than the fatalism of the latter ?
I'm with Rainboe .. if nothing else at least it fills in the time before you die.
