I believe that the Boeing Superjumbo jet is more efficient than the Dreamliner. This is because despite the Superjumbo having almost 50% more floor space and 60% more headroom than the Boeing 747-400, it is 50% quieter on take off.
I believe that your argument is absolute rubbish. The Z900 is the greatest aircraft to ever roam the skies (that aren't UFOs, BEAM ME UP SCOTTIE) and is much faster to take off than either of these. It is also the quietest aircraft in the world, and is, quite simply, the fastest. It can be used for military planes and passenger planes (Although those're called Z901s) because they always break the light barrier without even causing Einstein's theory of relativity to come into effect. The Z900 is better than either of these; shut up and stop posting your bad arguments about your bad airlines and realise that the Z900 is way better than that absolute tosh you call a Boeing Superjumbo AND the utter blatherskite you call a Dreamliner.
The Z900 is an aircraft, ever since Philip Zimbardo changed it from a bike to an aircraft a week ago. You need to learn that your aircrafts are inferior, and that the Z900 is the only aircraft that doesn't suck poo poo.
