So keeping below VNE means there is something wrong with the aircraft -- 
marginal design?
Keeping an eye on and reducing RPM in that Cessa 152 when it approaches 
red line means a marginal engine/prop design?

Sorry Al, this simply doesn't wash. It's called staying within operating 
limits and is standard procedure in operation of any machine. Yes, I 
know some are on a quest to automate and install safeguards to the point 
where the operator does not have to think or can't do anything wrong, 
but where is the fun in that? If you want to be totally safe, stay on 
the ground, in your house, in your bed (well -- that may not be totally 
safe either). To be totally "safe" is to stop living -- being dead.

So the trick is finding the middle ground -- don't do anything 
completely stupid and don't stop living either.
