I see we have some educating to do, very well, settle down and class shall begin...
Right, the first thing we need to do is establish why the Cobra MkIII is so much better than any of the other ships. I'd like you all to watch the following please, take notes, there may well be a quiz later.

Right, now to teach you why... DNA Decay, stop sticking gum in Aunties hair! Where was I, oh yes, I see several of you seem to think that the Annie is a contender well, let me tell you a little secret about that ship.
Not long after the first prototype was made a public information film was made but never shown. So bad was the ship considered to be that the film was sent back in time to 1982.
Now on to those poor people who think the Python is the best. As has already been pointed out the ship is actually an ancient alien vessel, these aliens were defeated by mankind back in the 21st century with basic guns and little to know ability to travel among the stars. Notice how mankind is still in charge on Earth? That's because the Python sucked then and 3,300 years have not changed that fact!
We should also spare a moment to think of those less fortunate than a Cobra MkIII pilot. The poor charity cases of the galaxy who are still stuck in 'Eagles'. Interesting fact about that ship, it was originally going to be called the Budgie but in a strange translation mix up it ended up being an called an Eagle despite it being good tapping bells and tweeting in mirrors!
NOTE: Excellent posts so far folks keep them coming!
