There is, of course, a catch: that 801-mph Vmax was the plane's ground speed, or the rate at which it was passing over the chilly landscape of PA below. As far as the 787 was concerned, however, it was still well within the performance envelope it was designed for, zipping along close to its established cruising speed of around 560 miles per hour.


How? It's a matter of airspeed versus groundspeed, of course.
