Why is it that the clothes which all awake people were wearing did disappear too when the plane flew through the time gate? These clothes were supposed to be found together with all the other items on the seats (watches, playing cards, toys, etc.). Also when returning to their rightful time by flying back through the time gate, Nick, who was the only one awake, had only his watch left behind, but nothing else, no shoes, no shirt, no trousers, nothing.
