How is the airship, Aurora, described in the novel, Airborn?

Aurora, one of many airships, is headed by Captain Walken. It sails about eight hundred feet above the Pacificus and has a crow's nest that is located one hundred and fifty feet above the Control Car, suspended from Aurora's belly. The Control Car has huge wraparound windows, but set back from the bow the way that it is, the visibility high and overhead is limited. As such, there is always someone on duty in the nest. Fully provisioned, she weighs a staggering two million pounds and is nine hundred feet from end to end - and is fourteen stories in height. Once filled with hydrium, however, it takes only two men to move her out of the hanger.
