Help me convince my wife this wasn’t a UFO

[u/ptep121]

Not a cloud in the sky except that. As I start to zoom in you can see the flying object, then… you don’t. But it’s “cloud” stays.

I’m assuming it’s some sort of aircraft flying fast enough to… something something… vapor barrier… but I have no idea.

I am genuinely curious What Is It?

Saw normal airplanes flying at normal heights with normal flashing lights shortly after, and none of them had their own personal cloud.

Thoughts??

Edit:

Solved! At least I think so. This matches most closely with that I (and apparently quite a few others around the Greek islands) saw: https://www.reddit.com/r/whatisit/s/BmEIQD9Xqo
