Remember when the pilot is taking the ship out for the first time and he's drifted to the edge and proceeds to scrape up the nose of the craft...
Well, considering how the ship is shaped, it would be impossible to fly as straight (practically) as he did and just scrape up the nose of the craft. The rear wing would have been destroyed in the process.
However, if the director acknowledges this mistake, it would ruin a great comedic moment.
