Some historically interesting links along the same lines:<p><a href="https://lifehacker.com/181548/build-the-worlds-best-paper-airplane" rel="nofollow">https://lifehacker.com/181548/build-the-worlds-best-paper-ai...</a><p>The first comment is particularly interesting. I have a very clear recollection of seeing the followup to the 60 Minutes episode he talks about. Back then, they would read snippets of letters they received from viewers at the end of the show. After the paper airplane episode (which I did not see, but wish I could find a video of) someone wrote, "You dummies! Show us how to fold the damn thing!" Which they then proceeded to do. Very, very quickly. Following the procedure in real time was hopeless, and this was back in the days when VCRs were still exotic new technology. We did not have one. But the memory of hearing Harry Reasoner (I'm pretty sure it was him) reading that snippet has stuck in my brain all these years.<p>If anyone can lay their hands on a copy of either one of these episodes that would be really awesome.
