In Superman 2, how do Superman and Lois Lane make it back from the North Pole after Superman removes his powers in that 'power removal machine'?
A few minutes after this scene, Clark and Lois are in a truck stop with American staff and American customers, so I'm assuming they've made it back to America.
If Clark can no longer fly, how did they leave the North Pole? They have no protective clothing or supplies so surely they couldn't have just walked could they?
