Ken, In my view comparing aircraft from different generations is like comparing cars from different generations,
I completely agree. That's why I did not compare "aircraft from different generations". I compared processes. Since the advent of jet aviation brilliant aircraft have been developed and built. Many of those brilliant aircraft did not do well in real world operations in their OWN time. That was not the fault of flawed design. That was the fault of flawed requirements. So once again,
IF the F-35 does not meet today's real world operational requirements, that is not the fault of flawed design. It is the fault (just as it has been for well over half a century) of flawed requirements.
