I saw a number of episodes of Justice League while it was still showing on the Boomerang network in the U.S. and noticed some changes in the superheros in the show from what I saw as a kid. One of them is that Wonder Woman can fly. I understand, from this questionthis question that this happened after Crisis on Infinite Earths.
I don't remember seeing any indication of Wonder Woman using her invisible plane in that series. When Wonder Woman was given the ability to fly on her own, was the invisible plane removed from the setting as no longer needed?
