On December 3rd my class went on a field trip to the MDA which stands for MacDonald Dettwiler and Associates. We were there to see presentations about unmanned vehicles, satellites, and radarsat. Each of them have something in coming to for defense. Detecting predators/enemies, search and rescue parties. Unmanned vehicles, give more safety, the jobs that are to dangerous for us make it no hassle. Satellites detecting territory knowledge and detecting mysterious satellites and ships. The radarstat keeps up with the defense and the growth with the underground heat with the industrial settings. The most funniest thing that happened during the presentation was the last one when Annnalisa popped out of the door and said she was lost. Funny moments, after that the presentation was worth while.
