the disappearing post on the plane that disappeared
The author of the vanished post claimed to have only recently found and read the thread on the missing 727, and stated that he had previously ferried airplanes to Africa. Presumably this both established his bona fides, and explained why he was so late in discoursing om a very long and quite old thread.
He then wrote comprehensively and with what seemed to be great (first hand?) knowledge on the whereabouts of several former AA 727's that were bought by operators in the Dark Continent. The detail was so specific, definitive, and dispositive that it would seem either he had access to logbooks, and/or unpublished government summaries of certain aircraft movements, or he fictionalized some of his data for some reason.
I personally think the former, and I sense the author may subsequently have thought he said too much, or revealed some things that are not otherwise publicly available.
Too bad, because it now only adds to the mystery.
