James Fox's latest chases Brazil's lost planet airmen
I've only read of this incident before, in summary. What struck me were the parallels with the Kecksburg case from 1965 and the documentaries by Stan Gordon and others. Varginha seems to be more complex. No military personnel came forward in regard to Kecksberg, as far as I'm aware.
I was going to say what the late Stan Friedman said in the credits - that the breadth of witnesses makes this a significant case.
Witnesses are complex data gathering entities, and more valuable than digitised radar returns (says the guy who's looked at lots of radar data). When one can combine complex sets of data together, then a clear picture can often emerge. James Fox has done another great service, to this field of research, by documenting so much information.
(Perhaps James can take a trip to Voronezh, when the current insanity has ended.)
