They answer: "Illegally"
An oldish drawing, about half a year, that I recently finished.
It runs along the idea of Raditz crashing or possibly running out of fuel of a plane and lands in the dessert. He hitches a ride on a train that happens to be going by where he stumbles on a stowaway, Rutatzu, who's hanging out in a compartment on the back of the train. They travel to a shop where Bulma is running a capsule facility where they pic up another plane.
It's not an actual story or anything, it's just a possible scenario to go with the pic.
