3-18-12, Minneapolis, 8:40 PM, 2 dots flying very fast from SE to NW, side by side, but offset, brownish color

A NW suburb of Minneapolis. I was outside in hottub at around 8:40 PM central time on the night of 3-18-12. It was very clear and a nice starry night. I had seen a plane (jet) just 30 seconds before flying from E to W very high over the Twin Cities at cruising altitude (like a NY to Seattle flight or something like that.) Then, flying roughly SE to NW at a higher altitude, I saw two dots, offset from one another-not side by side, like that of a plane, but, farther apart and nothing visible in between them. They were brownish color, much higher and much, much faster. That is why I say about 10 seconds because the plane I mentioned previously took probably 30-40 seconds to fly across my vision in the sky. This thing took about 10 seconds. It was definitely an object or one thing OR two things flying synchronized-which would be more my guess.
