Imagine you are playing with a toy airplane that you wind up with a string and then let go to fly around the room. Just like your toy, real planes can fly for a long time without stopping or needing more fuel. Sometimes, pilots try to break records to see how long they can keep their planes in the sky without stopping. This is called a flight endurance record.
To do this, the pilots need to make sure the plane is very light so it doesn't use too much fuel. They also need to be very careful with how they fly, making sure not to waste any energy or make too many sudden movements. They may even have a special team on the ground to help them plan the flight path and give them advice on how to conserve fuel.
When the plane is in the air for a long time, the pilots need to keep track of how much fuel they have left and when they will need to land. Sometimes they even have to fly in circles or figure-eight shapes to save fuel and stay up longer.
Breaking the flight endurance record can be very exciting, but it also takes a lot of planning, skill, and patience.
