Thanks Brian, I appreciate it. It was a team effort, and I provided regulatory guidance. The team was very receptive to my recommendations, and it shows. BTW - I forgot to mention, it went from an prototype to certification in 4 months time. In a few of my past lives this would have taken six months to two years.
