In 1955, two elderly sisters in Chicago, Mildred and Marie Maier, reported in the Journal of Space Flight their experiences with UFOs, including the recording of a radio program in which an unidentified code was reportedly heard. The sisters taped the program and other ham radio operators also claimed to have heard the “space message.” The CIA’s Office of Scientific Intelligence duly became interested and asked the Scientific Contact Branch to obtain a copy of the recording. Field officers from the Contact Division (CD), one of whom was Dewelt Walker, made contact with the Maier sisters, who were “thrilled that the government was interested,” and set up a time to meet with them. In trying to secure the tape recording, the Agency officers reported that they had stumbled upon a scene from Arsenic and Old Lace. “The only thing lacking was the elderberry wine,” Walker wryly cabled Headquarters. After reviewing the sisters’ scrapbook of clippings from their days as entertainers on the stage, the bemused and amused officers secured a copy of the recording. OSI analyzed the tape and found it was nothing more than Morse code from a US radio station. The matter rested there until UFO researcher Leon Davidson talked with the Maier sisters in 1957. The sisters told Davidson that they remembered they had talked with a Mr. Walker who said he was from the US Air Force. Davidson then wrote to Mr. Walker, believing him to be a US Air Force Intelligence Officer from Wright-Patterson, to ask if the tape had been analyzed at ATIC. Dewelt Walker replied to Davidson that the tape had been forwarded to proper authorities for evaluation, and no information was available concerning the results.
