"The Engineering Design and Analysis Laboratory was formed in 1965 as an interdisciplinary faculty group made up mainly of members of the College of Technology. The primary objectives are to give both faculty and qualified students experience in inventive engineering development where accomplishment is measured by actual results as much as it is by written reports. In the summer of 1966 the EDAL faculty undertook a study of different types of scientific sealabs, more properly known as Scientific Saturation Diving Facilities, for the U.S. Office of Naval Research. The "Edalhab" project began when the students decided to attempt building a model of the one their faculty were designing. The eight-by-ten foot Edalhab was launched on April 26, 1968 at Alton Bay, NH. Four student aquanauts spent 48 hours and six minutes living in the sea-laboratory they designed and built. "
