I’ve always wondered why only nuclear bombs detonate before hitting the ground and not the actual moment of impact. Does it affect the amount of damage? or does it reduce nuclear waste and radiation?

Reminds me of a story about one of my favorite High School science teachers. We were talking about atomic bombs and the incredible heat and energy — enough heat to disintegrate people and buildings that are close to the center. But, says my science teacher, you also get tremendous winds. Heat rises. Incredible heat rises quickly. As that heated air goes up, air must quickly rush in to replace it and that causes devastation that tornados only dream about. With an air burst, less heat is absorbed by the ground. “Why vaporize someone when you can push a building over on them?” says my science teacher. The bell rings and as we file out of class, he throws a thumbs-up at us, “So, keep ’em high!”.
