>That equation is irrelevant to the discussion at hand:

Oh yes it is, the faster you go you need to square your input energy even before you start to account for drag and gravity. Basic thermodynamics.

Where do you think that equation (D = CdρV2A/2) is derived from ?

Note the squared velocity term.

>as there is plenty of energy stored in the fuel tanks.

The more energy (i.e. mass) you have in the fuel tanks only makes matters worse as you have both an increased gravitational down force and energy required to reach your cruising speed.

Please don't throw equations around until you fully understand them.
