On April 16th, 2008, Mike Bara posted six URLs which were supposed to support his contention that NASA carefully concealed the results of the Viking biology Labeled Release experiment. In fact, his URL list did exactly the opposite -- supporting the actual truth of the matter which is that NASA made no such attempt.
Bara refused to allow this reply to be seen:
"I thank you for your six citations, which add further weight to the fact that no attempt has been made, by NASA or any other agency, to conceal this data.
Dr Levín is at odds with the "official" interpretation of the results, and indeed he has made some excellent points in the course of debating the question. That is a totally different issue from the issue of concealment. I'm sure you can understand that. Please correct your book in future editions."
