I honestly hope you are joking...
I know a hell of alot about airplanes, heck I even fly them, to tell you that that IS a MISSILE!!! Tell me, why would something that big (you say a DC-9) have such small wings? The dark spots you are seeing is a shadow of the ground. In fact, click this
link. Type in
Orlando International Airport in the search box. What you are seeing is beautiful Orlando International Airport, with four terminal buildings that are in a square arrangement. They are shaped like "T"s and "Y"s. Go to the bottom right "Y" shaped stucture. See the plane parked at the bottom right of this building? That's a DC-9. Explain how an object that's closer to the satallite gets smaller?
