The power = speed*thrust is valid and is a basic tenet of aero
engineering.

How much power is a B-29 generating during a full throttle run-up before
takeoff :-)

Having said this, I agree now that the equation accurately calculates the
increased power required to fly the same IAS at a higher altitude.
