Can someone offer a non-mathematical EXPLANATION (as opposed to
DESCRIPTION) of why the speed of headwind and crosswind components of
a wind add up to more than the speed of the wind?

For the same reason that it's a shortcut if you can walk diagonally from one
corner of a city block to the opposite corner, rather than following the
roads around the block.
