How a Zig-Zag Coast Guard Search Pattern Helps Save Lives

Take a trip to a Coast Guard command center.

Imagine this. You are on a ship in the middle of nowhere enjoying the deep blue seas and slow rocking motion of the boat. All of a sudden something goes wrong and the ship starts to sink. What do you do then?

You call the Coast Guard of course to come to your rescue. But how does the Coast Guard handle such a search and rescue mission? According to YouTuber SmarterEveryDay, it uses a zig-zag search pattern to carefully spot and outline your location and send the appropriate help.

The YouTuber takes us to a Coast Guard command center that tackles the area along the Gulf Coast of the United States. The officers there proceed to answer all his questions and show him firsthand how they operate.
