It all started with a visit to the micro air vehicle contest in Braunschweig EMAV 2004. There was a Multiplex Twinstar and Microjet that flew perfectly even though the weather was not nice at all. They had funny looking sensors that I had never seen on an airplane. It was great to find out that all the used hard and software was open source – Paparazzi. I got in contact with Antoine and Pascal, the fathers of the project. See the main page for the story.
