Pennsylvania - 12-25-11

My girlfriend and I were on our way to visit family Christmas morning. I was driving — she was the passenger, and we were traveling southeast on Route 23 through Valley Forge National Park.

As we approached the intersection near the park's Visitor Center, I looked up (towards the Visitor Center and over the outer line defense of the park) and saw a shiny, reflective, almost chrome-looking object in the sky.

It was spherical, maybe egg-shaped, and appeared to be stationary in the sky.

It looked a little like an old bubble-style helicopter fuselage... but it wasn't.

I asked my girlfriend jokingly if she wanted to bet if the object was an aircraft or a UFO. We watched the object for a few seconds.

I had to keep an eye on the road since I was on a curving hill coming up on an intersection, but my girlfriend was watching the object while fumbling for her camera phone.

Small tree tops obstructed my view for less than a second, and then the object was completely gone.

I think it shot off in a northwestern direction, but I cannot be sure. It was there one second, and completely gone the next.

My girlfriend was not able to get a shot off with her camera phone before the object took off/vanished. It should be noted that this sighting took place less than 2 miles from a Lockheed Martin facility.
