I can see the future of airline travel. You ship ALL your luggage separately on a cargo plane. At the airport, you strip & you package up your clothes for shipment back to your home. While nude, pass through security for x-rays & a cavity search, then you put on new disposable coveralls & sandals. After boarding the plane, everyone will be handcuffed to their seat. If you must make a head call, you will be escorted to the can & observed while using it. At your destination, you will be released & must immediatly leave the airport. Only people flying will be allowed into the airport. You have to apply at least 6 months before flying for a permit to fly. This will involve all the checks for a security clearance. Your travel docs will be encoded into a RFID chip in advance & will be implanted under your skin. The handcuffs prevent martial arts type moves being put on other passengers. What good are unbreakable cockpit doors if the hijackers say "Open up or we will strangle one passenger with a shoelace every ten minutes until you do"?
