As I was arriving at work I saw what I believe was an all white DC-8-60 series freighter as it was about to depart the New Castle County Airport around 10:20 this morning. It was quite a thrill to see the old bird take off I was too far away to get a registration or any owner marks. It was quit unusual to see a DC-8-60 among the C130's,privte pros and bus jets. I also did not know the runways were long enough to accommodate a DC-8 any information would be appreciated....thanks Dan
