It's 17 years, not 27.
Statistics are one thing, the real world is a different story.
Just because we didn't have a fatality that doesn't mean today's standards are the same as they were a couple of years ago.
Lately they are literally sending anybody with 3000hrs for their upgrade and the general levels of knowledge,experience and maturity are lower than they used to be.
I just hope not to be proven right by something unpleasant happening....
