As soon as I saw the patent image of the plane I thought of Di Vinci's Man.  I thought about the difference between how it might have been drawn in 1490 vs 1977.  Is there a Di Vinci out there today.
I am a history teacher and my learners and I have been studying the cold war and talking a lot about radiation.  Perhaps Mr. Farnsworth should have included a disclaimer,
