Considering this was the early part of the Space Age, I'm not sure the
information would have been available to the public. Much data was
classified automatically if it had anything to do with space flight.

forms of cancer involved. I'm not sure that more than 2 or 3 people
came down with the same forms of cancer: and there are a lot of them.
Also the DMH would have been in concentrated liquid form, which would
have vaporized extremely rapidly once exposed to air. If it took place
in FL or TX, vaporization could have been quite rapid. At any rate,
DMH was quickly removed from the experimental flight area.
