We travel to Dusseldorf for the Boot (Boat) show. One of the biggest in the world. The MS Watersports Jetlev-Flyer booth is big, the units are shiny, the price tags are 100,000 Euros. The audience watches the videos, but no one comes in to buy one. We start to question how big the market for 100,000 person flying devices. Flying the jetpack in the photo on the back wall is Philip, one of the early investors in MS Watersports.
