Very cool. I've been wondering on the upper limit on this for a while: Indefinite autonomous flight. Upper atmosphere or lower. I think I was inspired by SevenEves' gliders, but in my head, they would be small (er than depicted in the novel, and this article)

I think altitude is what would make these valuable. If you can approach LEO and away from standard military tech, they could easily prove refreshable tech platforms.
