I remember the dunker from the movie “Officer and a gentleman” from when I was 12, and remember saying to myself “well, guess I won’t be pursuing naval aviation”.
Drowning upside down: not for me.
They got rid of that dunker, and replaced it with a more evil helicopter simulation. The helo dunker was recently replaced with a more evil version that randomly flips to various angles. I think the airplane dunker was discontinued soon after I went through flight training. 1991 or so.
