According to information at the link above, there are about 100
"things" moving. That's one hundred times more opportunity for an
internal combustion engine part to fail in flight. Or don't you find
that fact significant?

Thats the brilliance of it... theres hundreds of moving parts, it's by
no means efficient or refined, yet there are more incidents and
accidents cause by the failure of natures most sofisticated creature at
piloting the plane than there are incidents and accidents caused by the
brute under the cowling.
