I did several tests on the Holloman track and I also worked in the lab at Wright-Patt that they showed. My rocket club did an outreach event this year at a STEM event and I talked to the contractors who had the latest test dummy there on display. It was very impressive. My team tested the original instrumented dummy on three rocket sled tests at Holloman and they are now using the third generation dummy. The electronics in our dummy were very primitive by today's standards and also very temperamental.
