I will start by admitting that I'm not very good at Crossfire. I actually struggled with the later missions in the original FL story and got vaporized by Nomads quite a few times. Even outside of the hard missions I seem to have a talent for finding new and entertaining ways to get blown out of the sky.
After making a lot of progress through the Crossfire story missions, I headed for Dom'Kavash territory for the latest mission, and encountered a Dom'Kavash gunboat, which shredded my shiny new fighter with its first volley. This is not the worst example of humiliation by far. I've collided with random torpedo volleys, planets and even stars while distracted.
If anyone else would like to share strange, unusual or just downright funny ways to fail in Freelancer or Crossfire, please join in.
