> the range is double, so that 737's can fly globe-spanning international routes now (this is game-changing)

And the price for that was the 737 Max, which cannot be made to fly safely but at least it only barely sips fuel when it crashes. Thank goodness it was designed by bean-counters rather than engineers.

This reminds me of a line from Snow Crash describing kids' pajamas, which can either be flameproof or non-toxic but never both at the same time.
