According to a blog post on United States UFO:
I exited the beltway onto Old Georgetown Rd. and turned right on Rock Spring Dr. which leads into the Office Park. It was shortly before 6 pm in August so still light out. On the left side is a High School (I'm not sure of the name - maybe Thomas Johnson H.S.?) Anyway; suspended above the school was an airplane just "hanging" in the air!This isn't the first UFO the person who reported it has seen. I've never seen one so either I am less observant or my UFO repellent is working.
