Never had any military experience, so not entitled to post here. BUT:
In 1961-62, at Aberdeen University Psychology Department, Dip Ed. Postgrad course concurrent with College of Education Diploma, over an evening coffee break one of the lecturers mentioned he'd worked on pigeon- controlled ballistic missiles. There was doubt if transistors could survive the forces, and valves couldn't.
There was a glass screen, with a metal grid. An aerial photo of the target was moved behind it. When the pigeon pecked at the target, it got food, and the wire pecked was to control the rocket.
When transistors were shown to survive, the project was ended, and he came to Aberdeen. I don't remember his name. Youngish guy then.
