Steve is the only survivor of the plane crash. The Amazons mount a salvage operation. One of the most significant finds of these sword and spear wielding women is the gun.
Sword and spear wielding on the one hand, true, but on the other hand, they manage to not only repair the nearly totally wrecked plane but to give it invisiblity too.
I don't believe it unless magic was involved - that story doesn't explicitly say so but that's the only way this feat can be justified.
There's a lot of discussion about the crash. This panel is representative.
As you can see, concepts such as 'the gods', 'omens', and such are the preoccupation of the Amazonian mind. I really like their analysis of the Navy Seal insignia.
Here's the conclusion of all this discussion.
Let the games begin.
We all know who the Champion is.
With that, Steve and Diana leave on the invisible plane.
