Show HN: Doomscroll the Goverment's UFO Files as One Gigantic Microfilm

It's still (I think) used in libraries for viewing newspapers and other things. I built a "Windows File Explorer" type viewer for the May 8th released files that are hosted on WAR.GOV but felt a single giant "timeline" was interesting and new enough to do one more.

Plus I think the problem of making the streaming of thumbs/full-size efficient and good UX for scrubbing, random seeking, and playback of documents and videos in one giant "reel" is interesting. Theoretically, it's a simple model: static files, fronted by CloudFlare, assisted by local browser cache and the goal is playback that uses bandwidth optimally.

Perceptually, I think it's a great way to "grok" a large amount of information. Your eye can notice things in the scan and you can zero-in manually to seek. It supports cursoring, and YouTube controls (numbered jumps 0 - 9 and j,k,l plus . and , for seeks and toggling playback) - as well as a bunch of touch gestures to scrub.
