Well, I was doing some research in WW2 materials & found this interesting video in youtube from a Japanese site.
I am very impressed with their gymnastic abilities. This is 60years ago, the trainees were usually university students much like our NS boys. However, during the last phase of the war, they were trained specifically to do only one mission. To die for their country by crashing their planes with 500lb bombs into enemy positions that were usually American warships. Aka Kamikaze.
Anyway, I'm not generating propaganda. Just wonder how many of us could do what they did in our NS days now. The training inside the rotating rattan cage is most likely for G-force simulation.
