Flew with a few ex Luftwaffe guys...one story was how few rolls one could do applying full aileron whilst flat out....and immediately centring the stick ...four and a quarter.
Don't disbelieve the guy as I mentioned putting the seat belt signs on in light chop..DC9-51 in cruise.....he looked me in the eyes...Turbulenz Alan...shoved the stick fully forward..then fully aft..."das ist turbulenz alan".
I was instantly white and wet.
Ironically he had a heart problem a few months later and was put in charge of FDR analysis.
