Older pilots will usually have more experience and less of a risk-taking mentality than younger pilots.
Yup.
Here in Arizona a few months ago there was quite a nasty accident with a single engine trainer with two brand new young pilots aboard.
No one knows exactly what happened as there was not a part big enough of the airplane to put in a shoe box...however, one of these new pilots was a known risk-taker, and had been re-examined by the FAA.
Not good.
