A more thorough explanation:

A logbook is a record of events that is kept by a ship or aircraft during each trip. It can also refer to any journal or record of events.

• A ship's logbook contains information about the ship's journey, including the route taken, weather conditions, and any notable events that occurred during the trip.
• An aircraft's logbook records information about each flight, such as the departure and arrival times, the number of passengers, and any maintenance performed on the plane.
• A scientist might keep a logbook to record observations and experiments conducted during a research project.

These examples illustrate how a logbook is used to keep a record of important information. Whether it's a ship, aircraft, or scientific research project, a logbook helps to ensure that important details are not forgotten and can be referred to later if needed.
