As has been said, he's intrepid enough and his determination is admirable. However, as is often the case in these matters, his disregard for his own safety could easily become his disregard for those that would be sent to rescue him.
We'll never know if it would have flown, given a long enough runway, but hiding at a disused airstrip which is too short, because your aircraft is not legal to use at a suitably sized one, is no way to start a cross Atlantic attempt.
We never did find out how he was going to stay awake for 40 hours either.
