quot;I watched a moon movie posted on Youtube by a HB of Apollo 15(?) astronauts planting the flag. It took about 30 seconds from being planted to stop moving after the astronaut left it alone (which was the main thing the HB had a problem with but which can easily be explained by momentum in space and some tension left in the flag and pole etc). What I can#39;t explain though is that the flag started moving again a while later when one of the astronauts ran past the flag without touching it.quot;Well, Youtube videos are fairly low resolution and high compression so you might not have seen a continuous motion of the flag. But let#39;s assume the flag really did start moving when the astronaut ran past - the pole could have moved due to vibration but the compression/resolution/contrast etc of either the original recording equipment or Youtube could have hidden this. Conspiracy theorists act like a Youtube video is a 100% accurate representation of reality, just Youtube search for 9/11...Also, (though I don#39;t know for sure) the astronaut#39;s backpacks may have vented gases from the life support system, much like a SCUBA system does, which could have created a brief gust of air that disturbed the flag.
