  The same engines they cancelled would have been used on LH2-fueled aircraft.

    Not viable. "An aviation-size, worldwide hydrogen supply and airliners capable of using it are decades and trillions of dollars away. In terms of a timely green return on investment, the money would be much better spent on SAJF, both for capital investments in capacity and for technologies that improve yields and reduce costs." - Alan H.

      AW is right that it will take decades and trillions of dollars, but the rewards are large enough to drive such investment. RR is acknowledging the long-term nature of the market and pivoting to shorter-term profit, probably correctly. You will not fly in LH2 aircraft, but your grandchildren will.
