I thought this was about the economic rates. $85,000 per flight hour per aircraft and 300 million per year for the fleet in 1990, from wikipedia. https://en.wi

  Well, as every pilot knows, what makes an airplane fly isn't Bernoulli's principle or thrust or fuel. What makes an airplane fly is money. Furthermore, there is a pretty direct relationship between the speed at which the airplane flies and the speed at which the money is used (albeit with many confounding factors). So one could say that this really is ultimately about that $85,000/hour cost.
