Johan Visschedijk: "In the period July 28, 1944 till October 31, 1947, the NACA used four BTD-1s for variable lengths of time, one for less than two months, another for almost three years. Two went to NACA's Langley Aeronautical Laboratory at Langley Field, Hampton, Virginia, and two went to NACA's Ames Aeronautical Laboratory, NAS Moffett Field, Sunnyvale, California. BuNo. 04971 was assigned to NACA's Ames facilities on May 18, 1945, and used for flying qualities, stability and control, and performance evaluations. It had been involved in ice research test when pictured at NAS Alameda, and was returned to the USN on October 31, 1947."
