“if you double the speed to fly from say London to NY, would you cut the time to fly to less than 1/8th what it would otherwise be?”
It’s bad, but not that bad. If you double the speed, you need 8 times the power, but only half as long for a given distance, so energy use is ‘only’ 4 times what you had.
(Of course, were talking about a very rough approximation that likely is so inexact that 8 might even be a better estimate)
