In these ruins of a Japanese temple on Ie Shima in WW2
 Appears to be A UFO.

In Temple ruin photo ,possible UFO ?
I think its a Blimp or Dirigible. Blimp I would think highly possible as they were used for Submarine warfare.  I put the photo on to AOL then blew it up 200 percent.  The lower gondola appears slightly distorted towards the front, but my  gut feeling is its a Blimp.  John from New York

When I was an intelligence officer in Bomber Command in the winter of 1943-44, I debriefed several crews about some lights that had attacked them when they were over the Baltic. They fired at the lights, which didn’t shoot back. These lights didn’t seem to do anything, just pulse and go round.
