To appear at one side and disappear on the other in 3 seconds would be about 39,000kph, nearly 6x faster than an X15. It would take an X15 about 18 seconds to cross the same distance. I’m not sure if it was exactly 3 seconds but it was faster than 5, and no way did it take 18.

Interesting. Traveling that fast (3 to 5 seconds) is a lot of G force for a human to endure. At 39,000 kph it would circumnavigate the globe in about one hour.
