    My engineer brain is breaking trying to understand how this could happen.

    Also, how the fuck does this work:

    By Thursday it had been lowered back to just several feet above the ground after firefighters cut a hole on the side and injected water to push it back into the ground.

    They did what now?

      From the article:

      The pipe’s unexpected elevation from the ground occurred at a sewer construction site where workers had been connecting an existing sewer line with a channel designed to hold excess rainwater to prevent flooding.

      The pipe was being used as a retaining structure to keep the surrounding soil from collapsing during the operation, officials said. A short time earlier, workers had drained water from the pipe, which may have caused the empty apparatus to float, they said.

        I… That still doesn’t make sense to me. Maybe I’m just having trouble picturing what this is even supposed to mean.
