Description

I came across this post (https://old.reddit.com/r/aviation/comments/10au3sp/dear_us_military/?…) on r/aviation titled *Dear US Military,* and for some reason the cross post button was not working so I uploaded the photo in question to this post.

I have never seen this photo before. Is it legit? If so, could this be one of the triangles that we hear so much about? What about the contrails in the back? Do these suggest that it is using a traditional propulsion system?
