Aeronautical Engineer Takes UFO Photo in England

An aeronautical engineer has taken a snapshot showing two clear UFOs over the River Dart in Devon. He had the camera examined and found that there was no dust on the sensor. Nine seconds after the objects appeared, they were gone. He knows this because he took two shots nine seconds apart. He did not see the UFOs when he was taking the pictures. Normally, UFO photos come in the form of blurs, but these are very clearly round objects, not birds or planes. Probable unknown.
