What vehicle?
Nepalese tourist bus on a winding mountain road.
I experienced this in Taiwan to less of a degree so thanks for making me never want to go to Nepal because that gives me anxiety just imagining it 😆
I feel like I’m taking crazy pills.
The speed of sound is 343 m/s, 767 mph. This description is Mach 5, 5x the sound barrier.
An F-22 can go 1500 mph.
Apparently the first airplane to break the sound barrier was Bell X-1 in 1947.
I think the intention is to highlight it as a milestone in the development of this aircraft. If you read the article, sounds like it hasn’t even been on a test flight yet.
Looks like the plan is for it to eventually reach speeds over 4000 mph.
The guy down the street with a Kawasaki Ninja probably thinks he can.
