Machinbird: I know a lot of pilots our age that are fine pilots. At some point you notice your driving skills and flying skills gradually diminish. Some at 50, some at 90.
We have all babysat a 55 year old captain to keep him out of trouble and I have had retirement flights with captains turning 60 that were the ace of the base. Age always gets you but not everybody at the same age.
I was told by a couple they could get me into their outfits flying but declined because I didn't need the money and felt fortunate to have 23,000 hrs and no incidents. Why push it? The late night stuff gets you first. We will see how this investigation progresses. Kind of agree that this was no demo flight at 3:30 in the morning. A lot of that was going on in the 70's when I was flying Lears into Mexico.
