That, combined with the target of opportunity involving the formation of IPX by UPS and DHL (for entirely other reasons), was the primary reason we are now an airline.

All the other silly stories that you commonly hear (including the truck lights) are simply cockpit fodder. If these stories help pass the time and add some amusement to an otherwise long, boring flight, no problem. Just take them for what they are. The only reason I jumped in was because one of these silly misconceptions was being used as an example to answer DCKozak's original question. There are probably many legitimate answers to his question, but that's not one of them.
