Yeah. It just extends the range of damage if you detonate at altitude. I’m struck by how the silos were protected by the effect of the crater wall directing the blast upward.
Yep - massive power always creates some anomalies.
Went through a tornado on Altus AFB in the ‘80s and the top floor of our squadron building was laid open like a doll house - roof and wall along one side gone - conference table was in place with chairs around it and folders/phones still on the table.
