Why do planes not fly over the Pacific Ocean?
Weather Patterns. Most flights are planned to minimize the time spent over bodies of water, since storms are more likely to occur over water than land. The weather over the Pacific Ocean is often turbulent, and there are many thunderstorms in parts of the Pacific, so it’s not a safe environment to fly a plane.

Do submarines hit whales?
Do submarines hit whales? A submarine hasn’t ever hit a whale. This is probably more due to whales successfully avoiding submarines, than the other way around.
Why are there no windows on submarines?
A nuclear-powered submarine is not based on a combustion engine. Unlike diesel subs, a nuclear sub doesn’t need air to burn fuel and hence can remain underwater for much longer periods. How is underwater navigation performed? Typically, submarines don’t have windows and hence the crew cannot see outside.
Is there a GPS you can use without WIFI?
