In response to a request by a "LTCol Davis" in April of 1937. The first SCR-271 radar (Fixed version of the SCR-270.) went to radiate on the Seventh of October, in 1940. "On its second day of operation, 8 October, the set picked up a commercial airliner flying down from Miami at a range of 118 miles and tracked it on its further flight.
