I do not count myself as a spoiler; just presenting my opinion. One reply from DaveP2 is really a work of art " If the planes didn't fly, the trucks wouldn't roll." Dave, you really believe this? Virtually all of the state Arkansas is served by FedEx Express trucks.
Also, in days after September 11th, 2001; all the domestic freight got to it's destination via truck (some of it was late but the freight rolled on trucks).
