The first newly designed CL-84-1 (CX8401) flew on 19 February 1970 with Bill Longhurst again at the controls. He continued with the CL-84 program until his retirement from active flying in January 1971. Doug Adkins then assumed the role of chief test pilot. At about the same time, at the height of the Vietnam War, the US Navy expressed interest in the concept. Atkins was dispatched on a cross-country tour that took a CL-84-1 to Washington D.C (landing on the White House lawn),Norfolk,VA and Edwards AFB,eventually full-blown trials on the USS Guam. The CL-84-1 performed flawlessly, demonstrating versatility in a wide range of onboard roles, including troop deployment, radar surveillance and anti-submarine warfare.
