  I signed the Official Secrets Act so I can’t give away too many details! What I can say is that I worked on guidance systems for cruise missiles. I was very young and inexperienced so I didn’t achieve much though.
  
  Looking back on it, I deeply regret working for a weapons company. I have better things to do with my time than think of ways of killing people.
