Long time readers of the blog know of my plan to streamline passenger plane loading and unloading. My idea is to mount the seats on a sled, have the passengers seat themselves at their leisure at the gate, and then have the sled rolled onto the plane in one piece. We've come that much closer to the plan with the development of the Boeing DreamLifter cargo aircraft. The tail swings open so that large items (such as sleds full of passengers) can be rolled right on. The next question is, do people want convenience and efficiency, or windows.
