Originally that was posted during Memorial Day weekend here in the States, so many folks were probably out and about and missed it.
And originally it was posted for only the Memorial Day celebration by YouTube, it was to have been posted for only a limited time, then taken down.
Thankfully the documentary makers have left it up, and apparently are posting it elsewhere for others to see, it is a great short to watch nonetheless.
So really anytime its gets posted again, that's a good thing. It's great to watch over and over. ;)
