Unknown over Edgemoor, DE

The report, as filed

I was driving to work this morning around 8:10. I looked up in the sky to see a very long contrail that was actually being created in front of me by a flying object that was not visible. Day was sunny. By my angle, I should have seen sun reflecting off of the object-but none seen. No lights seen. I could see the vapors billowing out of the invisible object so it was pretty close or just very big. Only at one point do I think I saw the object making the contrail but it just looked like a cloud in the shape of an oval. It moved very fast. Faster than a commercial plane. To give an idea of relative speed: it was similar to a helicopter flying at a quick speed: however, he object was much higher than a helicopter. The trail seemed to have make a dark aura like line from as far as I was able to see. I heard nothing.
