This past weekend I saw the Jurassic World movie for the first time. Just as in all Jurassic Park movies, what starts out as an exciting journey with the possibility of viewing real live dinosaurs soon turns into a disaster. In the movie, a couple of boys are sent to the park by their parents during the holidays. A dangerous new dinosaur escapes as they are riding one of the park’s exciting attractions and the characters are unaware of the danger around them. When their aunt tries to contact them using a cell phone, the signal is unreliable and the call ends up dropping. While it was a great dramatic effect for the movie, it brings to light the need for two way radio communications.
