They both make the same sort of noise if they hit something
just that some of their
pilots make a very different noise before or after...
and some of the military noise here sounds simply unprofessional for me as human errors can be easily corrected and avoided once understood.
If pilots have a problem with their own personality they maybe don't like to look at the human factor, scared to see their very own incompetence?
ps: their incompetence as 'humans', not necessary 'pilots'
