747 Large Cargo Freighter

Take one 747-400 passenger aircraft and cut away the upper fuselage at the main deck floor beams. Then cut the tail off and adding a couple of rather large hinges. Splice in a larger bonnett, add another X foot long section to the vertical stabilizer, add a huge machined (flat) pressure bulkhead (what I'm working on) just aft of the cockpit and viola, the worlds largest cargo aircraft (by volume).
