Jimmy and his group were nervous and were closely monitoring the movement of the flying saucer. With Captain Jack's authorization, the nuclear button could be pressed at any time.

The Noah where the people were located was still too close to the alien spacecraft, only more than 130 kilometers away. If a helium-3 nuclear bomb detonates directly, it is likely to affect itself!

But there is no way, it is an act of death to hold back against alien civilizations. Captain Jack clearly knows that the new human civilization is not much stronger than a grasshopper in front of the real interstellar civilization, and the nuclear bomb is their last protector. Before the tetrahydrogen nuclear bomb came out, the helium-3 nuclear bomb was the most powerful weapon for mankind!

Anyway, the Noah is also a product of a super civilization, and it should be fine if it is affected by a nuclear explosion...
