As soon as we witnessed this UFO, I called my husband who is a MUFON State Section Director as well as a Field Investigator & was in contact with him throughout the entire event to give him a full description of what was going on, but unfortunately we could not get a good picture at all.1. We just left the Oxford Valley Mall in Langhorne, PA and were in the car coming home.2. I saw something flying in the sky and it appeared to be sparkling.3. I had absolutely no idea what it was-I thought it was a little too exotic to be an airplane. I was in the front passenger seat and asked my friend's daughter- who was sitting in the rear drivers seat- to look at the object flying in the sky. When she moved over to my side of the car to look out the window- she freaked out.4. At first it appeared to be a u shape- but after I got my friend's daughter to look at it with me it appeared to be oval shaped. It was so bright and appeared to be glittering with colors not associated with airplanes. Yes, there were red, green and white lights- but also Lime green, pink, magenta, purple, orange and yellow- with a gold background. It was shimmering and glittery- (it reminded me of holding a diamond ring under a bright light with all the facets reflecting color.) The colors were more heavily concentrated in the front, but were all over the oval shape. It appeared to be 3 inches long and 1 1/2 inches high out the window, where I didn't need to really extend my neck to look up at it. It remained in sight the whole time we drove and was anywhere from 12 to 18 inches behind my line of sight.5&6 I got this tingling sensation up and down my right arm but was not afraid. It was actually the most beautiful thing I have ever seen. I couldn't take my eyes off it. I kept laughing while my friend's daughter was freaking out. I called my husband to tell him about what we saw and he told me to get a picture of it. My friend sped up and pulled into a vacant lot. As we jumped out of the Minivan, the object approached and turned right. It changed into a straight line. As we attempted to capture it on film, it dissapeared.
