Guy may have been a wannabe fighter pilot. A sim can simulate any type of feature. I’m a heavy guy but fascinated by fighters as I never touched one in real life.
Pretty sure he didn’t need a sim for a 777 seeing as he was certified in one. It’s not like he can do some stunt flying on a revenue run.
I too have never touched a Fighter ... Been pretty close to ‘em though but that was only once at an AF base. Drove by and looked and kept my distance.
