At the end of the 1960s, under the guidance of Mike Sekowsky, Wonder Woman surrendered her powers in order to remain in Man's World rather than accompany her fellow Amazons to another dimension. Wonder Woman begins using the alias Diana Prince and opens a mod boutique. She acquires a Chinese mentor named I Ching, who teaches Diana martial arts and weapons skills. Using her fighting skill instead of her powers, Diana engaged in adventures that encompassed a variety of genres, from espionage to mythology. This phase of her story was directly influenced by the British spy thriller The Avengers and Diana Rigg's portrayal of Emma Peel.

Gerber and Frank Miller pitched DC on revamps of the “Trinity.” The three titles would be called by the “line name” of METROPOLIS, with each character being defined by one word/phrase… AMAZON (written by Gerber); DARK KNIGHT (written by Miller); and Something for Superman – I believe either MAN OF STEEL or THE MAN OF STEEL, but I’m not sure about that (written by both men).
Wonder Woman continued to use the plane for super speed, outer space, and multi-dimensional transport up until the unpowered era of Diana Prince. When Wonder Woman resumed superpowered, costumed operations in 1973, she continued to use the jet as before, but did glide on air currents for short distances. At one point, Aphrodite granted the plane the power to fly faster than the speed of light for any interstellar voyages her champion might undertake. Thanks to tinkering by gremlins, the Plane even developed intelligence and the power to talk. The plane proved a good friend, eager to help his "mistress" and her loved ones in any way possible. It got along especially well with Steve Trevor.
Granted by Athena (Goddess of Wisdom), this gives her a degree of wisdom beyond that of most mortals and gives her a strong moral sense. Originally in the Golden Age, her wisdom primarily consisted of her deep knowledge of, and ability to navigate through, human emotions. When she first showed up in Man’s World, she learned enough English language to converse with others in a few hours only. This also aids her in her tactical ability. She is among the smartest and wisest members of the Justice League of America, along with the Martian Manhunter and Batman.
“As to the ‘advanced femininity,’ what are the activities in comic books which women ‘indulge in on an equal footing with men’? They do not work. They are not homemakers. They do not bring up a family. Mother-love is entirely absent. Even when Wonder Woman adopts a girl there are Lesbian overtones,” he said. At the Senate hearings, Bender testified, too. If anything in American popular culture was bad for girls, she said, it wasn’t Wonder Woman; it was Walt Disney. “The mothers are always killed or sent to the insane asylums in Walt Disney movies,” she said. This argument fell on deaf ears.
