It's a movie. If Val Kilmer (in "Tombstone") can get three shots out of a side by side shotgun and 32 shots out of two 6 shot revolvers, anything is possible.They would most certainly have to reverse-engineer all of the systems on the Nimitz. and sequester all of the crew. Possibly even create a naval version of Area 51 for the Nimitz. What about spare parts for the carrier and the aircraft? The metallurgy for manufacturing the planes didn't exist back then.
