Would any poster in this thread who doesn't "believe in" reflected
power kindly explain how a transmission line can fail upstream of a
serious mismatch anywhere along the the length of that line. If that
doesn't result from the sum of forward and reflected voltage/current,
then (IYO) what is the reason such failures?

Don't think that this doesn't occur. I've seen it many times, and had
to find and replace the molten and arced-over components that
resulted.
