7. Dallas Wings (7.01 miles)
This one was also problematic, so I will accept gripes with this measurement. I started by looking at the Wings’ logo, which clearly depicts the winged horse Pegasus — a creature from Greek mythology. The question should then be how high Pegasus could fly. Believe it or not, I’m far from the first person to ask this question. In fact, here’s a study from the Department of Physics and Astronomy at the University of Leicester that studied what size its wings would need to be to fly. And these people here discussed how its bones would need to be hollow for it to fly at all. Nobody that I encountered in my research seemed to account for magic. As in, Pegasus is a mythical creature, so it does not need to obey the laws of physics. So let’s say, because we can, that Pegasus could reach the height of the highest known bird on Earth. That is Ruppell’s Vulture, which can reach 37,000 feet, or just over 7 miles.
