#29: Supercarrier
As enormous and terrifying as this ship seems for megalophobia, there’s even more of it under the water. Trust me, if you’re already feeling the fear, do not look it up! These supercarriers are insanely large. The Knock News, an oil tanker, is over 1,503 feet long, while the Maersk Mc-Kinney Maller is 1,309 feet.
