Nice to see some rational comments instead quick leaps to erroneous conclusions.
Not a UAV. Shot in July of 2001 from my plane window using a MiniDV camera using a slight zoom that appears to be optical, but may have been digital. The 480p video is so crappy from the get go it's hard to tell.
I was honestly amazed that we were flying that close to another airplane. Here's a better shot with no zoom to give a better perspective. You can see the window sill in the lower-left corner of the image.
Obviously there were parallel runways.
Not sure which airport this is, as I was doing a lot of flying back then. I was coming back from Thule, Greenland. So this was an International airport on the East coast. Probably the Delta hub in Atlanta.
I was on a commercial flight once and we passed a jet going in the opposite direction so close that I could easily see the passengers on the other jet. Startled the heck out of me
