That's really comparing apples to oranges.

At the airplane industry it's the government that does this calculation, with a publicly known value of C. Also, airplanes don't have the kind of problem that cause an accident by itself, every issue can be corrected on several levels, and normally when the proper fix isn't instantly applied some other action is done to attenuate the problem.

On any advanced country, around here it calculates nothing, even yelling "Are you insane? Do you know how many hospitals we could build with that kind of money?" won't make they think about numbers.
