Let’s be clear on how strange perfectly conventional objects can appear in a photo. These 8 examples were taken using a smartphone camera, and they demonstrate the lack of clarity and proof that is in a photo.
The objects were all identified as aircraft, by sight and sound, before the photos were taken. The camera was held steady, with no effort to distort or lessen the quality of the photo. This is not to say that photos are not proof, but a lot of value is placed on these candid shots, and we always have to be wary of what we are seeing in a photo, because tricks (errors) of perspective, distortion, and resolution are very effective at obscuring what we are really seeing.
