The Invisible Plane was a creation of Diana's during her younger years on Paradise Island. She created it to be an improvement on her mother's planes which would be shot down in Man's World. The result of her innovation was an invisible plane that could fly at terrific speeds silently and not be detected by hostile forces. Initially, it was portrayed as being transparent.
When she is preparing for the final game (Teaming up with Supergirl, Starfire, Bumblebee and Batgirl against Lobo, Maxima, Bleez, Mongal and Blackfire), the competition is interrupted by Lena Luthor. Wonder Woman starts putting civilians safe, including the Embassador, who, out of fear, orders her to star with him to protect him. She refuses and returns to the batlle, angering the Embassador. She fight Lena and then Brainiac. Upon their defeat, Wonder Woman rejoins with her mother, thinking she dissapointed her by no following the Embassador orders, but Hippolyta is proud instead, stating that Wonder Woman will be an amazing Queen.
William Marston's earliest works were notorious for containing subversive "bondage and sapphic-undertones" subtext. Among Wonder Women's infamous catchphrases, "Suffering Sappho", was a direct reference to lesbianism. Fredric Wertham's Seduction of the Innocent referred to her as the "lesbian counterpart to Batman" (whom he also identified as a homosexual). After Marston's death in 1947, DC Comics downplayed her sexuality and feminist origin. Wonder Women, without Marston's creative direction, become more "traditional" superhero fair; the lesbian relationships and sexual imagery disappeared from the "Wonder Woman" comic, along with Wonder Woman's super powers. During the Comics Code Authority-decades since, Wonder Woman's subversiveness had been gradually stripped away; subsequent comic book writers and artists either didn't know know what do with her or barely hinted at Wonder Woman's erotic legacy. Similar to whitewashing, Wonder Woman's queerness and feminist identity throughout the latter half of the 20th century was never discussed and rendered "invisible" in adaptations in favor of the dominant sexism portrayal of women in comic books.
Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors. Trevor's legacy was also the primary reason why Ares arranged for Steve Trevor to bomb the island, as he could not resist the irony of the heroine's son unwittingly killing her admirers.
