As Orlando grew in size and importance from a small cow town with a few defense firms to an entertainment and research center, MCO had grown as well, adding flights, adding congestion and eventually adding runways. But the main runways were the same that had been laid down in the 1950s and they were more than adequate to handle an F-15. Which was how Dr. Weaver arrived after a flight from Andrews Air Force Base he would remember for some time.

FAA regulations prohibited military jets from breaking the sound barrier over inhabited areas. Jets which were supersonic, therefore, were limited to training over water or uninhabited desert areas.

Bill Weaver had flown in F-15s before, including aerobatics to try to make him sick. They hadn’t. But this was radically different. The F-15, carrying conformal wing tanks, had climbed for altitude at what was called “maximum military thrust.” Since an F-15 is one of the very few aircraft in the world that has more thrust than mass, that meant virtually straight up for a minute and a half. It was very much what he imagined being in the shuttle would be like, if you were able to look around in every direction. When it reached its optimum altitude, 65,000 feet, it had turned south and the pilot had pushed the afterburners to full. From that high it is normally hard to notice the change in motion relative to the ground at all. Just as high jets look as they are moving slow from the ground, from the air the ground itself tends to look stationary. Not at darned near Mach Three. It had taken thirty minutes from when the pilot turned south to when he flared out for a landing in Orlando. And the earth, which from their altitude had a very distinct roundness to it, looked as if it had shifted rotation from west-east to north-south. Even at their height Bill was pretty sure they’d left a string of broken windows behind them.
