Project Overview:The UAV project was formed because of the lack of senior projects that dealt exclusively with Aeronautics engineering
Goals of the Project:To design, build and fly a UAV that could be assembled from a suitcase

First Test Flights:On April 13 several attempts to get the Bixler to fly autonomously end unsuccessfully when the Bixler suddenly darts out of control and crashes
