Reading comments in the B-29 thread about the cool advanced technologies developed towards the end of WW2, I thought someone might be interested in this program to use trained pigeons to guide missiles. It's from.......and the rest of the site has fantastic info on a whole range of other technologies, many of them from WW2 as well.These notes were taken from an interview with Skinner...In modern terms this is a passive, trained neural network guidance system. A pigeon's brain is a much more powerful and robust neural network than any we can build today. Pigeons are also light and easy to "maintain". This guidance system can't be jammed and as it is passive, gives no warning from emissions such as radar. This is all an excellent combination.All in all, a seemingly good idea that shouldn't have been dismissed so quickly.Cheers, Neilster
