Another story I've read is that the fact that the SRB's were built in segments instead of one single long tube is that 80' is about the maximum length a rail car can be built and negotiate curves. While it's true that a longer booster could have been built and air transported (the pregnant guppies) there was an attempt at the beginning of the shuttle program to involve as many states and industries in the process to "so to speak" spread the wealth to keep as many congressmen in the yes vote column as possible. <br /> <br />Bob DeWoody
