Underwater UFO Mystery Surfaces

I'm going to let a picture of the famous "Spaceship House" from here on Signal Mountain suffice for an introduction to this post. You see I've always enjoyed a good science fiction book, television show, or movie. I grew up watching "Star Trek", and was bananas over "Star Wars". And I can't count the times I have watched all or part of "Sphere", which combines diving and the discovery of a UFO wayyyyyyyyyyyy down deep. So today imagine my surprise and interest in a legitimate UFO mystery that has been discovered underwater.
A dive team has located the wreckage of an Air Force F-89 that went down in Lake Superior in 1953. Like all good mysteries this one began when a radar operator reported a UFO and the F-89 on the radar screen merging into one image, then disappearing.
Today's sonar allows divers to look for wrecks and find them with amazing resolution even hundreds of feet deep. If you have ever seen "Deep Sea Detectives" you know what I'm talking about. So the images have been released of this plane wreckage and the UFO today, and you have to check them out at http://www.divester.com . Make sure you follow the links to see all of the pictures and the historical account of what was being reported in November of 1953.
What's awesome is this mystery will surely be solved with time. There are very sophisticated remotely operated vehicles or ROVs that can explore such deep sites. And this story has enough intrigue to make an awesome episode for "Deep Sea Detectives" or some other show.
There's probably some very simple answer to what the round object is near the aircraft. But on the other hand...........it brings to mind a line from the movie "Contact". Jodie Foster's character looks up at the night sky and says, "If we are the only ones, it seems like an awful waste of space."
