Was on a photo shoot. Observed very high up what appeared to be a jetliner.
Had a 700mm telephoto lens on and photographed the object.
Upon checking and magnifying the file on my computer, I found that it did
not appear like a regular aircraft. The object was very high, therefore,
not the best quality to look at, however, enough to be able to have an idea
of what it may be. (photo attached)
