The talk is called "Flying Linux" and was an invited presentation at the latest USENIX.org conference. The talk is wide-ranging (from real-time operating systems to digital fly by wire to ...) and is sure to include something that you will disagree with or be offended by. Nevertheless, the URLs are below.
One thing that I found interesting was his discussion of interfaces to vehicles like segways (http://www.segway.com/). Note that Segways don't have steering wheels (like cars) or reins (like horses -- or the Phelps tractor!). Here are the slides and movies and the talk.
