ALEX CAMPBELL'S TUMBLELOG

Rockets—at least, the kinds that are destined for orbit, which is what we are talking about here—don’t go straight up into the air. They mostly go horizontally, since their purpose is to generate horizontal velocities so high that centrifugal force counteracts gravity. The initial launch is vertical because the thing needs to get off the pad and out of the dense lower atmosphere, but shortly afterwards it bends its trajectory sharply downrange and begins to accelerate nearly horizontally. Consequently, all rockets destined for orbit will pass over large swathes of the earth’s surface during the 10 minutes or so that their engines are burning. This produces regulatory and legal complications that go deep into the realm of the absurd…

Moreover, the rocket industry’s status as a colossal government-funded program with seemingly eternal lifespan has led to a situation in which its myriad contractors and suppliers are distributed over the largest possible number of congressional districts. Anyone who has witnessed Congress in action can well imagine the consequences of giving it control over a difficult scientific and technological program.
