Nearby boiler explosion?

Sort of thought that, but we haven’t made a cast iron boiler since around or before WWII... Compressors and engines are still made of cast iron and could have gotten that hot before coming apart at speed and/or pressure. A good size Detroit Diesel two stroke tacked out would throw pieces a pretty good distance...

I don’t know. I mentioned it to Darksheare because he’s involved in ballistics and lives in the Northeast :-).
