I really find it hard to believe that suicide has yet to be mentioned in this, I do not mean to say that he took off with the intention of dying, in the sense of Lubnitz. However, it is very possible that his planning had the intention of death should his fuel planning strategy not work it (as we know... it did not work out). The final act of flaps down, gear down and nose down, as not the actions of anybody that wants to live after losing all power. The Captain would have known that the likely outcome of reaching the airport would have been an arrest, closure of his business, prison and bankruptcy for his family. Compare that to the out come of his death, being, no prison, possible obfiscation of the facts, the company survivng (he wasn`t to know that we would all know the truth in numbers) and a hefty insurance payout...
... Has this crossed anybody else's mind?
