Skyfan.. agreed and thanks for confirming what I had heard. Wish I'd written a few books in the past !!
Regarding pictures.. I've been interested in UFOs for nigh on 60 years and I've yet to see a convincing photograph or video of a "true" UFO. I'm not sure that such pics exist. Somebody showed me a video clip recently of what was supposed to be an unusual craft - which it might well have been - but it had a flashing red anti-collision beacon suggesting that it did not originate from outside of Earth! I live in hope, though.
