Nature is pityless -- woman sucked out of plane.

[Anomalocaris]

One would think that there is a better engineering solution to prevent such future tragedies, say, better shatter proof glass.

Of course, officially, Southwest wants to pray.

When you look at the numbers, number of engines that exist, number of hours they spend in flight, number of fan blade failures they experience, you realize the current level of engineering is more than adequate to insure excellent levels of public safety. You probably have a better chance of being crushed by a meteor while also being bit by a shark than you have of being killed as a result of turbine engine fan blade failure.

Using the consequentialist approach, one evaluates how many lives are statistically likely to be saved by strengthening planes against the consequences of a comparatively rare form of failure, and weigh that against how many more lives would likely to be lost because the cost of such enhancement, when passed onto the passengers, will cause some of them to forgo airline travel but adopt another way to travel, all of which are statistically more dangerous to life and limb than airline travel.

You don’t want to invest so much in airline safety that you price airline travel out of reach for more people and drive enough of them to getting hit by cars to offset any safety you gain with airplanes.
