Huh, it seems that the Astronauts and their families, had complete faith in their co-workers and their superiors at NASA. It is very easy to point out a memo or something but their is no rebuttal to this memo only except a little blurb from someone.
It is very disingenuous to stroll out this memo and imply this former NASA administrator is correct. He did not "predict" the insulation falling off during liftoff and damaging the tiles, but what the hey it is convienent for TLB to trot this and say "see, see, NASA is evil and I am the all knowing one".
Everyone from the Astronauts to the enngineers to the Astronauts families knew the dangers of space travel, but it seems that TLB is only concerned with trotting out some unsourced memo, to taint NASA as evil, and smugly and falsely say, "I told you so". And that is beneath contempt, IMO.
