Today climbing on an airplane as a pax gives me the willies.
This is more likely down to personal psychological factors.
As has been previously stated, accident rates are far lower now than 40 years ago - some of this is down to more reliable aircraft, much is also down to a shift in attitude on the flight deck - thankfully (by and large) ego on the flight deck is dead and buried as is risk taking behaviour. I would send my family away on any of my employer’s several hundred aircraft on any day of the week in complete confidence - the system works.
