    en.wikipedia.org/.../High-altitude_nuclear_explosion

    The visual effects of a high-altitude or space-based explosion may last longer than atmospheric tests, sometimes in excess of 30 minutes. Heat from the Bluegill Triple Prime shot, at an altitude of 50 kilometers (31 miles), was felt by personnel on the ground at Johnston Atoll , and this test caused retina burns to two personnel at ground zero ...

    en.wikipedia.org/wiki/Nuclear_shaped_charge

    About 85% of the bomb's energy could be directed into the target as plasma, albeit with a very wide cone angle of 22.5 degrees. A 4,000 ton spacecraft would use 5 kiloton charges, and a 10,000 ton spacecraft would use 15 kiloton charges. [1] Orion also researched the possibility of nuclear shaped charges being used as weapons in space warfare ...

  9. Uncontrolled decompression - Wikipedia

    en.wikipedia.org/wiki/Uncontrolled_decompression

    The risk of lung trauma is very high, as is the danger from any unsecured objects that can become projectiles because of the explosive force, which may be likened to a bomb detonation. Immediately after an explosive decompression, a heavy fog may fill the aircraft cabin as the air cools, raising the relative humidity and causing sudden ...
