Not only did they broadcast the explosion they also caused it. Haha(not funny)

Richard Feynman was the one who let slip innocently what the cause was during an international press conference and made a lot of people in Washington very very mad.

Basically, the Whitehouse pushed NASA to launch despite the weather being too cold and that caused an expansion joint of an SRB to fail.

Feynman showed the world what happens to the expansion joint material by putting it in some ice water for five minutes during the press conference and showed it crumbled after he took it out of the glass.

That man was an international treasure and I miss him very much.
