Yesterday afternoon I photographed a Boeing 777-300ER flying over my home, according to radar data it was at approximately 32,000 ft. In the photograph there is another aircraft present, it is much smaller and higher in altitude (40,000-50,000 ft) and it is a small aircraft, possibly a drone or military. It did not appear on any flight tracking sites. I usually see military traffic flying in that particular route and heading. I have numerous "raw" images of this particular aircraft.

I originally though it may be an L-39 although that particular aircraft does not have a T tail design and I think that it would struggle at that altitude. The photographs were taken at 1545 EST. over the LVZ VOR.
The aircraft was flying an almost perfect east to west heading usually reserved for military traffic.
One interesting note is that it was not leaving a contrail. I routinely photograph B-52's, tankers, and fighter aircraft transitioning over my home at or about that altitude and they almost always leave contrails.

  I asked a co-worker who flew U-2 and he says that to his knowledge all the wings used have a taper on the rear. But he has not flown ALL the variants. Also he points out that there are no visible pods for sensors, which is common with operational flights. Plus the paint schemes on all the U-2 that he has seen as operational are low reflectivity paints, and would not appear as in the photo. How about giving us more data on your photo acquisition details?

Using the location you gave, I tracked back aircraft in that area at that time, and found a scenario that fits with your photo:

So, judging by that, the jet in question is actually a Learjet 31, as said by John K.

Here are some blueprints, and the dimensions are similar:

  I did a bit of pixel measuring. In the image, the Boeing 777-300ER is 87 pixels long; the Learjet is about 12 pixels long. A 777-300ER in 75 m long; a Learjet 31A is 15 m long. Putting all of these numbers together, we can infer that the Learjet was roughly 1.5 times farther from the camera than the Boeing. That's not too far off from the reported altitudes of 32,000 and 45,000 feet, particularly if the OP was at a higher elevation.

I'd say it's a corporate jet. Corporate jets normally play between 40-55000 ft, above the bulk of the airline traffic down in the 30s, so this is a perfectly normal sight.

Based on the wing planform with straight trailing edge and swept leading edge, and what looks like a T tail and ventral fins, I'm going with Lear 45 or a similar Lear variant (Service ceiling 51000 ft). The viewing aspect doesn't look like from directly below so the engines won't stick out very clearly.
