Here is an entertaining promotion being run by ABC and Disney at the Comic-Con convention in San Diego. Comic Con, by the way, bills itself as the largest comic book and popular arts convention in the world. In this case we have a mock passenger cabin of a Pan Am airliner, full of early jet travel gibberish. It's a come-on for a situation comedy to be called -- what else -- Pan Am, which will air this fall. If you're too young to remember any of this, you have got to watch to see how your parents flew. Or maybe your like me and actually did it.
