So, where's the flaw? Does anyone else see the flaw? Is there
a flaw? Is Nescio here the only one who sees a flaw? A flaw he won't
identify?

I did identify the flaw.
You can't seem to grasp it.

Is this a serious, enlightening discussion or some sort of
aviation Trivial Pursuit?

A little of both, IF......you actually want to learn something.

Try this one:
You launch a missile at the moon. Halfway there you check it's
free trajectory and find that it will hit dead center in crater X.
Suddenly it explodes into a million pieces, all spinning off into
space in all directions. What happens to the center of mass?

Depends, Plain or peanut center?
