2006-04-07 - in the air - Other

I was flying between St. Louis and Houston to a graduate school event. It was my first time flying on an airplane, and so I insisted on a window seat so that I could look out the window for the entire trip. So as I am in the air (I am not exactly sure over what state and at what altitude), I am looking down, and I saw a perfectly-spherical object, it was much smaller then the 737 I was on, but probably twice as big as a car, and it was moving in the opposite direction of the plane. It was moving very fast. It was like it was made out of steel. I was staring in disbelief at this object, trying to figure out what it could possibly be. Then, as the sphere was almost out of my field of vision (I was sitting on the left-side of the aisle in the airplane), another object came into my field of vision. This object was moving at exactly the same speed as the sphere and it looked to be made out of the same shiny metal. But this object was not a sphere, it was a triangle or a pyramid.
