That's just before and after the OSHA inspector showed up.

Anyone here familiar with that sort of demolition work who can tell me why you'd want to spend months slowly chipping away at something like that as opposed to a explosively-triggered implosion?

Seems like they clipped it specifically to the area that is just inward of vertical.

The local Tony's Grocery has chicken feet for $2.29 / lb.
US Government Inspected, no less. So now we know that our tax dollars, in some small part, pay the salary of a federal chicken foot inspector. https://cimg3.ibsrv.net/gimg/www.mia...8f3a23d30d.png |

It was the last big linear supply that we did. After that, we went with switchers. Anyway, the lab decided that as part of the validation, they'd bypass the overcurrent protector, short-circuit the output, and apply unlimited current to the input. The inspectors' report read, in part: "Smoke and flames were observed to radiate from the device." |

This reminds me of an event about 20 years ago, during the UL certification process for the power supply that PR&E was designing for the Airwave audio console.
