one mission seems to have become forgotten - none of the TV documentaries even mention it - Apollo 4. This launch took place on Nov 9th 1967
Not without its problems - the sound from the first stage engines was so loud that it almost demolished the studio from which Jules Bergman was broadcasting, several miles away. Another problem which showed up on this launch was the power suddenly drawn by the TV crews tripped out the launch control power supply, this could very easily have been disastrous, but fortunately the Saturn V (on its first flight) behaved perfectly. From then on, NASA insisted that TV crews provide their own power feeds, and the concept of "battle short" was introduced to Launch & Mission Control centres - the circuit breakers were jammed in so that power supply was guaranteed - it was considered less dangerous to have a single circuit melt than potentially lose the lot because a circuit breaker popped out.
