A Pennsylvania witness is reporting a silent, low flying craft near Allentown Airport on May 26, 2010, that was 400 to 500 feet wide and approximately 150 feet long, according to testimony from the Mutual UFO Network (MUFON) witness reporting database.

The witness also reports that planes were flying above the object at the time of the sighting.

"I could see the frontal 4 windows and the full bottom of this greyish craft flying over perfectly and immediately sketched the craft on paper," the witness reported.

No sketch was provided with the report.

The following are the unedited and as yet uninvestigated reports filed with MUFON. Please keep in mind that most UFO reports can be explained as something natural or manmade. If Pennsylvania MUFON State Director John Ventre investigates and reports back on these cases, I will release an update.

Pennsylvania, May 26, 2010 - Flew north to south at approximately 100 feet off ground silent and huge. MUFON Case # 23618.

While watching TV I saw a light coming from far off. At first I thought it was helicopter. As it got closer the object went from white light to off green glow then dark with frontal glow. I got off the couch to go outside thinking it was helicopter to hear the sound. There was no sound it flew in straight a line coming at me while I was looking at it in the alley, no side to side movement just straight and silent. This is 2nd time in 3 years this has occurred.

This object was about 4-5 hundred feet wide and about in center 150ft. thick nose to tail. It was so low I could have thrown a rock and hit it.

I am deeply concerned about this.

There were planes coming and going to the south out of Allentown airport and not one changed course as this object continued right under them. This is no joke I am serious. My dog didn't even bark at it, he went back to the door scared. I have tried to contact people about this and have had no luck in doing so.

I could see the frontal 4 windows and the full bottom of this greyish craft flying over perfectly, and immediately sketched the craft on paper. This is the second time in 3 years on a cloudless night. I don't know what it was but it wasn't military. Sincerely
