Mornin' Quix.
Here was Stan's reply:
"A few references might be useful. My congressional Testimony at the hearings of July 29, 1968, is somewhere on the Web (Symposium on Unidentified Flying Objects - Hearings before the Committee on Science and astronautics). It is in two parts and includes 65 references, a list of 10 patents for circular aircraft and a copy of an article Flying Saucers ARE Real with more references. The volume has 11 other papers by Hynek, Sagan, McDonald, Menzel, Sprinkle, Harder, etc
My 1974 MUFON paper, Flying Saucers and Physics, is 18 pages, 2 columns and has 69 References. It is still available from me at POB 958, Houlton, ME 04730-0958 USA for $4. which includes shipping.
My 1999 MUFON paper, Star Travel? YES!, is also 18 pages long and has 18 References... also $4. from me.
The above cover a lot of ground, but not much about very
speculative far out propulsion systems. Magnetoaerodynamics, fission, fusion... are all discussed."
