Another more feeling perspective is that in healthcare, errors cause real harm to individuals that you see and care for on a daily basis. Most errors can be attributable at least partially to a specific human that care for the patient. This surely has much higher psychological damage than a very occasional loss of 200 passengers that are not even your countrymen in a plane crash, or a loss of a few million dollars that is not even your own money to begin with.

I imagine there must be at least some who have gotten it correct, and perhaps the issue is that the best coding practices for stable systems haven't been propagated far enough, but I don't think that 99.9% of companies have this ship fast and fix it later philosophy at least.
It's not an easy problem to solve I'll admit, but I don't think that stems from the tendency for most software firms to want to push out features quickly.
