Francis
Ridge:
This one was not listed in the original PBB Unknowns, but is listed in
the updated version by Brad Sparks. I ran into it while looking for
something else on the BB Microfilm site. There were incidents of UFOs,
radar-jamming, and unexplained nuclear radiation on both the 29th and
the 30th.
