It is very clear that the aviation industry is NOT risk averse. They are averse to losing money (via needing to spend money to redesign systems, recertify interfaces, re-train pilots, rebuy new equipment and simulators, all of those reduce risk but are capital intensive). But they are no longer risk averse. They might never have been risk averse at all - the roots of the aviation industry is exceedingly risk seeking in the first place (to fly is itself a risk seeking activity - and that's something understood by all pilots and all aviation and aerospace engineers on day 1 of wanting to fly) You can say the civilian oversight groups that seek to regulate the industry are risk averse, but the companies that build the planes themselves, if they had their say, we'd be flying mach 3 upside down all day.
