You have to buy the book to see the picture ..
There was a guy who cut a 36er wheel into three pieces to fly. It's counterintuitive but a few pins are all the existing joint typically needs, so two more can work too. He'd build up the wheel in baggage claim with the frame as a jig and ride off.
Seems a little easier with a pneumatic tire than rubber retained by a twist and solder wire.
