That hardly ended the controversy. In February 1943, Josette Frank, an expert on children’s literature, a leader of the Child Study Association and a member of Gaines’ advisory board, sent Gaines a letter, telling him that while she’d never been a fan of Wonder Woman, she felt she now had to speak out about its “sadistic bits showing women chained, tortured, etc.” She had a point. In episode after episode, Wonder Woman is chained, bound, gagged, lassoed, tied, fettered and manacled. “Great girdle of Aphrodite!” she cries at one point. “Am I tired of being tied up!”
Shortly thereafter, Wonder Woman is shown being able to summon it with her tiara, have it hover by the War Department, and extend from it a rope ladder with which she could board it. She uses the plane to fly into outer space, and frequently transports Etta Candy and the Holliday Girls, Steve Trevor, and others. During the 1950s, the plane becomes a jet, and is often shown swooping over Lt. Prince's office; she strips out of her uniform at super speed and bounds to the plane. Though the Plane was depicted as semi-transparent for the reader's convenience, in-story dialogue indicated that it actually was completely invisible, or at least able to become so as the need arose.
Having learnt of Wonder Woman's inability to return to Themyscira, Doctor Veronica Cale, a wealthy and powerful woman, set into motion a plan to use Wonder Woman to find Themyscira. Years earlier, Cale's daughter Izzy had her soul stolen by the gods Phobos and Deimos. They told Veronica that they would only return her daughter to her if she helped them find Wonder Woman, and got the location of Themyscira from her. Seeing no other option, Cale had formed a team called Godwatch, dedicated to locating Diana and Themyscira.
