Hi Bob...

I made the remark about Jean flying for 30 minutes or so
each time she flew was to make the point that she was "72 years
young"" and ONLY flew for pleasure.

....

Point taken. And like many others, please accept my sincere sorrow
and condolences for all involved. No matter our speculation about the
causes or how to prevent accidents, this one occured, at great loss to
those involved, and at some loss to all of us.

Bob
