Most people around now don't recall when Apollo 4 launched.
NASA hadn't worked out the suppression system, and windows were blown out miles away. Seismographs in New England picked up the vibrations from the launch in Florida.
Walter Cronkite was reporting from a block house miles away. You can hear him talking about the window panes (special windows for the block house) shaking and them trying to hold them in with their hands. the ceiling tiles starting falling and part of the rook got peeled back.
You can hear Walter Cronkite start talking about that just as the video ends.
