Science fiction proved wrong !

One movie I saw about flying was Iron man , it was about a super hero who wanted to fight crime and used a jet pack to fly and save a people. Glen Martian may have proved that someday we can all fly. The Kiwi engineer showed TV1 viewers how high his super fans on his Martian jet pack can go. To be careful he had to use a dummy first to test fly his jet pack to see if it was safe for him to fly.
It was a magnificent day for New Zealanders because it was the first jet pack to fly 5000ft.
