Really? I read the article but waxing and putting the tank in the fuselage I find hard to believe that an F-100 had trouble keeping up with him in a B-57.
B-57 top speed is 598 with cruise at 476. Thrust to weight ratio is .36
F-100 top speed is 877 with cruise at 587. Thrust to weight ration is .55
Kind of hard to believe that wax and removing the drop tanks could affect the speed that much, but anything I guess is possible. And I'm a bomber person, I want the bombers to be better....
