AROUND THE WORLD IN 5.5 HOURS
We read it was an experimental aircraft, tested in the sixties, but it just shows that when we think we we’re going fast driving our car, it is really slow in comparison to how fast we could be traveling. If a person can get around the world in around five hours, then we imagine they could bounce from time zone to time zone and experiment with time travel in a sense.
There are many other aircrafts that can circle the world in less than a day. The North American X-15 is pretty impressive, but there are supposedly unmanned aircrafts than can make it around the Earth in just a few hours.
