I worked on the Cluster project as a software developer for many years, at the University of Sussex in Brighton. My first job. And it blew up. Great first job. I was watching live with hundreds of engineers and scientists at Rutherford Appleton Laboratory. There was silence. All we could hear were birds singing, coming over the satellite link. Quite an experience. Amazingly, the Cluster project got up and running with replacement hardware a few years later, and I was back on the job.
