A video included in an article in Hemming's daily newsletter (screen shot above):
The article about Milford fired off a few long-dormant synapses for me. One of the very first tasks I was assigned when I hired on with Ed's Famous Data Company back in 1985 was to be part of the QA team validating the installation of a new PBX at the proving grounds. I spent a weekend at Milford verifying everything worked properly and went through most of the buildings where there were phones. The facility was in a "minimum manning" state, given it was the weekend, but there were still quite a few people there who were quite happy to explain their jobs to visiting firemen, which included a couple of impromptu facility tours. The video above focuses on safety testing but there's much, much more going on at Milford. One of the more interesting things I saw were examples of "competitive analysis," whereby GM acquired competing models from various and sundry brands and tore them down to bare bones in the evaluation process. I remember seeing a brand new BMW 7-series going through corrosion testing... which involved placing deep (and precise!) scratches on various body panels and immersing the car in salt spray for hours and hours... and thinking "what a WASTE!" I saw ALL sorts of cars at Milford that weekend, ranging from the mundane to the exotic, including quite a few testing mules of new GM products yet to be released to production.
The Milford proving ground is a wondrous place, indeed.
