In The Sherlock Society, what does Yadi want to use to search for the planes that disappeared in the Bermuda Triangle?

• A. A drone
• B. A satellite
• C. A submarine
• D. A helicopter

Answer: (A)

The main idea here is choosing a practical, flexible tool for an aerial search over a wide, potentially dangerous area. A drone fits that need perfectly: it’s unmanned, quick to deploy, and capable of staying in the air long enough to survey large stretches of ocean. With cameras and sensors, it can relay real-time imagery and data, allowing the team to spot debris, heat signatures, or other clues without putting people at risk.

Satellites cover broad regions but don’t provide the close-up, timely data that you need for a focused search, and the imagery can be less actionable in the moment. A submarine would be useful underwater, but it won’t help locate planes that disappeared on the surface. A helicopter can do aerial searches too, yet it’s more limited by weather, fuel, and operational costs, making sustained searches less efficient.

So, for Yadi’s plan to search for missing planes, a drone is the best fit.
