RADIO OPERATORS SENIORITY LIST

Flight radio operators were employed 1947 - 1954. They communicated with ground stations by Morse code during ocean crossings. Some radio operators do not appear on any available seniority list. The blue dates were found through examination of online crew manifests. They are the date of the earliest manifest found as yet listing that person as a Seaboard crewmember. The actual dates of hire are unknown. An asterisk indicates an estimated date of hire.

The era of radio operators ended at Seaboard in 1954 when the new Super Constellations and remaining DC‑4s were equipped with high‑frequency communications radios that enabled the pilots to communicate by voice with ground stations over long distances.
