It's easily possible, I could do it if I had to. The challenge isn't flying the Dodo it is fighting boredom and your daily life. I do two laps around the city and get bored and land. I'm guessing he paused it while he slept.
I remember back to the days of the bastard Dodo on the PS2 how it frustrated thousands and many thought it was impossible to fly, though some were gifted enough to fly it. The best part was the look on my brother's face the first time I showed him and how he was very angry at me for making it look so easy. He said "How the hell are you flying it, you fly it like its a real plane, that's not even possible!" Haha
