Maritime Self-Defense Force YS11 flight experience(1984)

This is a video of a flight experience of a tour of Beppu Bay on a YS11 airplane belonging to the Maritime Self-Defense Force at Oita Airport on August 10, 1984.
Dad, mother and Hanako participated with their neighbors.
At one time, 50 people boarded a YS11 plane and traveled around Beppu Bay. After taking off from Oita Airport, they landed at Oita Airport by passing over the coastline of Kunisaki, the mountains of the Kunisaki Peninsula, Marine Palace Aquarium(Umitamago), and Kitsuki.
Since it's summer, the cooler isn't working in the YS11 before the engine starts, so it's cool with a Uchiwa (a round fan).
On this day, my father, mother, and Hanako came home with great satisfaction.
