Step 1 : Introduction to the question "Which superhero travelled around in an invisible plane?"
...Wonder Woman was created back in 1941; her first comic was released right around the time of the attack on Pearl Harbor. When you think of Wonder Woman a few key weapons come to mind. She possesses an arsenal of advanced technology, including the Lasso of Truth, a pair of indestructible bracelets, a tiara which serves as a projectile, and, of course, her invisible plane. The invisible plane was Wonder Woman's primary mode of transportation for long distance travel. The Invisible Plane appeared in the very first comic stories, including All-Star Comics #8, where it is shown as being able to fly at over 2,000 mph.
