      can you contextualise this? I thought it was about the flying manhole cover

      During the Pascal-B nuclear test of August 1957,[8][9] a 900-kilogram (2,000 lb) steel lid was welded over the borehole to contain the nuclear blast, despite Brownlee predicting that it would not work.[8] When Pascal-B was detonated, the blast went straight up the test shaft, launching the cap into the atmosphere. The plate was never found. In a conversation with Bill Ogle, Brownlee estimated its velocity as “six times the escape velocity from the Earth”—approximately 67.2 km/s (150,000 mph).[10]

      hence this thing being posted here more than once.

        It’s the floating roof of an oil storage tank outside Moscow, Russia that got destroyed earlier this week. The video makes that gigantic piece of steel look like it thinks it’s Wash from Firefly. Just a leaf on the wind.

        Terrifying.

          ok makes sense, thanks.

          I saw the video… wat? I don’t watch firefly, I don’t like westerns.
