a "mature market" that "is in maintenance mode?" Time? The extent of poor and neglected, overdue maintenance?
Of course, planes operating successfully still outnumber those which disintegrate in normal use. But it's not just planes. Consider that collapsing bridge in Minnesota recently. Consider also the Tacoma Narrows fiasco, now some decades ago, which in my opinion is not a mistake that competent engineers make, but one due to social promotion at the highest levels of our education system, which is also symptomatic of an empire in decline. Consider how much of our electrical grid depends on nuclear plants that are at, near or even past their originally estimated lifetimes but not being decommissioned in short because of lack of competence and political will to replace them with better alternatives, and consider how desperately we still depend on 19th century fuels, coal and petroleum, despite what we know about their effect on climate. I think gp AC makes a valid point, using one plane to illustrate a far more widespread, and very real systemic problem.
