Saturday, October 18, 1958 - A new landmark was added to the Dauphin Island landscape today when the 693rd AC&W Squadron, the Air Force unit manning the new radar site, erected their "bubble" atop the central tower. Major Ira Adams, commander of the unit, said the "bubble," a large dome shaped device approximately 50 feet in diameter, is erected to protect the radar site's vital and sensitive equipment. It is made of a rubberized fabric material and is inflated by air pressure. (History editor's note: the frame is visible today as part of the Sea Lab's Estuaruim complex.)
