Re: Dum dum dum dum dum
One pilot is acceptable in short haul flights: attention spans are minimised, the weather and the need for alternate flight plans won't vary *that much* in the vast majority of short flights and the planes tend to be smaller with fewer passengers to worry about - the whole deal is significantly less complex.
However, long haul? If nothing else, if you only have one pilot, who's in charge when they need a pee? And when one of the 200 passengers decides to throw a tantrum and the pilot (who has ultimate management responsibility) is asked to intervene, who looks after the ship then? And you're sure one person has the capacity to deal with a flame-out while also planning an alternate, talking to ground, making sure the crew know what to plan for AND keep everything fairly level 'cause I'm not convinced.
