What is the greatest distance from its launch site that a failed rocket (or its debris) has landed?
- Failures only. This excludes surface-to-surface or surface-to-air missiles, which are intended to hit a target. Also excludes missiles that are targets for anti-missile weapons.
- Launch only. Exclude spacecraft that have reached orbit, even if they later fall out of orbit.
- Include the debris of a rocket that was destroyed because it was malfunctioning.
- Landing off-target is covered in this question.
This question asks in part about the specifications for range safety used to place a launch site in Florida. If such information is public, then it should be answered there. Otherwise, the answer to this question gives a good idea of how large a "safe area" would need to be.
