First of all, nice sight, John. It's always fun to take a jog through history.
In answer to markuz226, politics again rears its ugly head. The government cannot arbitrarily give contracts to whoever it wants. They have to be "impartial" and accept bids from anyone who wishes to compete. They may have already decided which one they want, but they can't show favoritism toward a specific company or designer. Too many lawsuits.
