A bright light to the northern sky, then goes dim as it leaves.

At approx. 7:30 EST, I was watching an airplane coming from the east going west.  The plane crossed over and could not be seen because of trees. 
My wife was standing a few feet away leaning against the truck as I was looking up into the northern sky.  I seen a real bright light and I said,"What the hell",   my wife looked up to where I was looking and asked what is that as the light got dim.  
I said I don't know what that was, but it was no plane as it was way to far away.  It looked as if it was a plane coming down at a 90 degree angle with it's headlight on.  The light was bright, then went dim as it dissapeared to the sky.  I thought it could have maybe been an after burner from a Stealth plane, but I do believe it was way way to high to be one. 
It looked as if it was heading towards a star in the northern sky.
