I'm not a regular visitor of the aviation exchange, and know very little about the topic so wanted to make sure my question would be on topic.
Today a relative showed me a picture that contains what appears (to my unknowing eyes) to be a quite irregularly shaped contrail (vapour trail?). At the front of this is a (to us) unidentifiable "object". The one showing this picture claims that the trail can only have been left by a rocket. However I don't think that is the case but rather some kind of small agile plane (but don't know enough about aviation to really be sure of that either). I have a rough time and location estimate for when the photo was taken.
If you need the picture in question to be able to determine if it would be on question i'm happy to post it, but will refrain from posting it initially to not sidetrack this question to answering that question.
