John started to work on his hydroelectric engine for his ship, when he was surrounded by aliens, with the one John has met a few times before, and it said "Just give up, you're not going to leave"
After that sentence, the aliens busted up his ship. All those years work, ruined. John got so mad, he started beating the alien, till it started to bleed, when the other aliens pulled him back. John gets the impresion that he is the head alien, which turns out to be true.
The aliens throw him to the sand, and dissapear out of thin air. John stares at the wreckage, and starts to rebuild. It doesn't take as long as it did before, because he knew what he was building 100%. After the ship was finished, he hid it, and started working on a lot of oxygen tanks, because he soon had a long trip.
