I get suspicious about these - a low time pilot, no experience or
instruction with aft CG, maybe a little show-off to the many friends on
board. I shouldn't speculate until the NTSB gets done.

But why is it that a disproportionate number of crashes happen with all
the seats filled? Do instructors cover that situation (both technical
and psycological(sp?)) in a private pilot course? They should.
