I don't have much details on this but I am looking for a clip that apparently used to be played on US television late at night, probably in the mid/late sixties. I think it may have been last thing, like the close of the channel.
It was some black and white footage (may have been a plane or ship) with a man's voiceover.
I actually saw it ages ago on an episode of Mad Men where Pete Campbell fell asleep in front of the TV and it was playing. Can't remember which episode or season though.
I vaguely remember looking it up at the time and watching it on YouTube, and it appeared to be quite famous but I can't remember enough details to find it again. Any assistance is appreciated!
