Okay, little buddy! Imagine you have a toy helicopter. Sometimes, it might break or need new batteries to work well again. Just like your toy, real helicopters sometimes need to be taken care of too!
A hangar is like a big room or house for helicopters. When they need to get fixed, they go into the hangar. Inside the hangar, there are people who know how to make the helicopters all better. They check if everything is working right, just like we check if your toys are okay.
So, when a helicopter is in the hangar, it's resting and getting a little makeover to make sure it can fly safely again! Just like how you feel better after a nap or when someone helps you when you're feeling sick.
That’s why helicopters stay and get fixed in the hangar!
