Bob Bastard used his jet rocket to redirect an asteroid towards The Gruntmaster 6000 to simulate an asteroid crash. He launched into orbit from the testing site, and deployed a probe.
The probe directed an asteroid towards the test site, but Dogbert used a laser to break up the asteroid, and the probe returned to the launch bay inside the fighter. Bob then attempted to destroy the Gruntmaster 6000 himself by steering his fighter towards the testing site, intending to ram it. However Dilbert and Alice moved the exercise machine out of the testing area, and Bob could not pull up in time, destroying his fighter in the process, though he survived.
