 I'm getting some bandwidth to put more work into my book about Boleslaw Gladych and his connections to the gravity (and antigravity) research communities that included characters like Agnew Hunter Bahnson Jr. during the 1950s.  I found an article [pdf], (pamphlet? it's 42 pages), that sheds more light on the woork DeWitt did with superconductors and gravitomagnetic fields in the '60s. Take a look at page 34 where DeWitt comments on his work to try to verify Bahnson's fringe pet project: Thomas Townsend Brown's gravitators. There you'll find a reference to DeWitt looking into superconductor theory .  I also found a nice little JSTOR blog post on the whole Babson and Bahnson Gravity Days era. I haven't seen anything new in it yet, but I aslo haven't taken the time to focus on it. Speaking of DeWitt, this history of the UNC Field Institute is interesting in that it mentions DeWitt's work related to 'large spaceships'.  One final note, Wolfgan...

+Jonah Miller  wrote about back of the envelope calculations today and it inspired me to finally write about the oft-quoted by fringe scientists work of Bryce DeWitt and the surprisingly less quoted work of Robert L. Forward. The link between Forward's work and Jonah's article is that Forward wrote an excellent pair of articles entitled "General Relativity for the Experimentalist" for the Proceedings of the IRE[1], (the precursor to the IEEE), and "Guidelines to Antigravity" for the American Journal of Physics[2].  In these two articles, Forward encouraged scientists and engineers to do back of the napkin general relativity by using a method of linearizing Einstein's field equations in in the weak field flat space limit so that they could be treated in the same manner as Maxwell's EM equations. So, where does Bryce DeWitt fit into the equation?  In 1966 he wrote an article about using superconductors to to detect gravitomagnetic fields...
