The electronic controls were ambitious and advanced for the day. The navigator and DSO's cockpits featured wraparound dashboards with warning lights and buttons, and automatic voice messages and warnings from a tape system were audible through the helmet sets. Research during the era of all-male combat aircraft assignments revealed that a woman's voice was more likely to gain the attention of young men in distracting situations. Nortronics Division of Northrop Corporation selected actress and singer Joan Elms to record the automated voice warnings. To those flying the B-58, the voice was known as "Sexy Sally." - Wiki

Bitchin BettyWikipedia names Kim Crow as the first woman to provide digitized cockpit voice warnings to military aircrews. That’s true, but it’s a truth hinging on the word “digitized.” Joan Elms was of the pre-digital age, recording her warnings on old-fashioned magnetic tape. To my knowledge, the B-58 Hustler was the first military aircraft to employ aural cockpit voice warnings, and Joan Elm’s was the voice behind them.
