KCTV5 News, Weather, Traffic and Sports for the Kansas City Area B-52 Mistakenly Drops Bombs on Nearby Lake: “Jordan said the bombs, all of which apparently hit the water, were filled with concrete, not explosives, and didn’t pose a threat to the public.”

The bombs were safe because they were filled with concrete and only could have crushed the swimmers.

Thats the connection, concrete bombs
