Author and researcher Bill Grabowski joined George Knapp in the first half to discuss his exploration of the work of John Keel and the Mothman incidents, which involved anomalous aerial phenomena, Men in Black (MIB), and bizarre electromagnetic intrusions.
Author and ufologist Nick Redfern followed in the second half, addressing the hidden, overlooked, and buried history of humankind from ancient aliens to the New World Order.
I used Photoshop to zoom in to the trails but have not altered the image in any way, shape or form other than that... I verify that I took these pictures with my iPhone in Mountain View CA. while driving on Shoreline Blvd. about 1/2 mile away from NASA Ames Research Center between 12:17-12:32pm on Tuesday September 23, 2013... The interesting thing about these pics, besides the unusual shape and size, is that they seemed to appear out of nowhere. No clouds in the sky, and no planes flying over to create these. Maybe someone has information about these, but I've never seen anything like this before.
Update: Check out this rotated and sheared photo from Andrew P. which indicates that the image was created by a skywriter.
