It created a fireball 5 miles in diameter, destroyed all buildings up to 34 miles away, and could give 3rd degree burns to people 62 miles away. I can't even comprehend how one bomb could do so much damage.
Notice the scale by zooming out ever so slightly. Also, time scale, because it happened decades ago.
This has to be the only man-made destruction that can bee seen with the naked eye from space.
No, you can see Los Angeles from space.
It was more that 50 years ago. Now...
Basically if the explosion was any bigger it would leave the atmosphere into outer space so there is no point in making it any bigger.
