qweaver, listen up. "induced" drag does indeed go up by the square of the
speed. *however* the ***horse power*** required goes up at the sum of the
induced drag plus the additional hp needed for increased speed. in other words,
hp needed goes up at the cube of speed.

of course, *you* are not required to believe anything you don't understand, or
don't wish to "when presented with a valid arguement based on facts".
