I don't think you quite get the engineering challenges of building a hypersonic aircraft.

It's not just a case of slapping bigger engines on. The demand for a passenger scramjet isn't high enough to offset development and maintenance costs.

For moving large payloads, we're not moving away from turbofan any time soon.

  1. Aircraft don't run on gasoline

  2. You don't need to design a plane from scratch for a new engine. BROADLY speaking it's mainly the horizontal tail that needs to be redesigned to account for the pitching moment from the engines. The problem with hydrogen is its lower energy density than aircraft fuel. It's the reason why electric jets don't exist

  3. This would probably be for future aircraft not retrofits.

  4. You clearly have no idea what you're talking about.
