Look at pictures of Nagasaki and Hiroshima after the bombings - there are partial buildings standing where everything around them is totally flattened.
You're trying to look at pictures and deny the reality of what happened by asking idiotic questions based only on paranoia and a penchant for conspiracy theories. You act as if you are some kind of expert in the dynamics of explosion, and refuse to recognize that these types of explosions involve a certain amount of inherent randomness in their actual effects.
