What is the best method of transportation?

@LeMagicBaguette Maybe not so much, we are talking about a flight from the USA to the Middle East at a speed of 2000m/s which is less time, remember that you can set the time speed to x2 or x4 but if it is better to use space.Thanks for the contribution

Hypersonic air travel is a really, really bad idea for long periods of time. At those speeds, it's better just to fly out of the atmosphere entirely.
