Strange Space Craft - likely hoax

Earthfiles has this note:

Around May 11, 2007, Coast to Coast AM webmaster, Lex, received an email letter with attached May 6, 2007, images of a very odd aerial object from a Central California resident who calls himself "Chad." Chad is worried about his family's safety and health since he has now seen the bizarre aerial object at least eight times from his house windows and on hikes near his home. Neighbors, he said, have also seen the unidentified aerial object. Then on May 15, 2007, I received another similar aerial "drone" image allegedly taken by a person at Lake Tahoe, California, on May 5, 2007 and identifying themselves at UFO Casebook.com as "Lake Tahoe-05-05-07MUFON Submitter 7013."

These pictures were originally posted on Coast to Coast Am, also showed up on the Mufon website, and are owned

C) http://www.mufoncms.com/files/7013_submitter_file4__Craft050607c.jpg

Additional similar were posted on the MUFON website, these from Lake Tahoe

3) http://www.mufoncms.com/files/7013_submitter_file2__070505_03.jpg

Chad owns the first pictures, but the implication is that the second set is from somebody not connected to Chad. But notice that the close dates on the pictures, and the fact that they were posted by the same user on the Mufon website. If the numbering is correct, Chad IS Mufon submitter 7013

Note the names of the files, and note that the first three files are identical to the ones posted to Coast to Coast AM

There is nothing here that could not be done by one person with multiple email accounts, etc. These web sized pictures are not good enough for analysis. It's pretty obvious that nothing that has been posted has been good enough for actual analysis, which is exactly what a hoaxer would want.
