The source is here: https://www.reddit.com/r/CatastrophicFailure/comments/adl0jk...
I wrote this. I noticed it jumped 12,000 views and I got no username mention on Reddit, so I asked around and found it came from here. Made an account just to post the source. I'm pretty pissed that someone linked it completely without credit.
As for what it is, it's part of a series I write for reddit where I read as many sources as I can about a plane crash, write it up in a way that's understandable to laymen, and then post it for others to read. Taken away from me and my reputation on Reddit it has zero credibility because it's just a random album on Imgur.
