Ask a funny joke about flying for the first time.

I am a mechanical and electrical major. This is my first time to go out by plane. I saw a lot of empty seats next to me, so I changed (before taking off). A sister-in-law next to me saw me change places, and he also changed places with some coconuts. I don't know that the plane has started at this time, and it is in the acceleration stage, and the engine room makes abnormal noise. The whole plane is nervously looking for sound. My first reaction at that time was that the sound made by machinery was in a high-risk stage of take-off and landing, and it was over.

When I looked back, my eldest sister-in-law was staggeringly standing in the aisle, and her coconut fell all over the floor. That eldest sister-in-law said it was the first time to fly, and I didn't know it would happen.
