Read "The Checklist Manifesto" and you understand why pilots follow their protocols. Outcomes like this are because they did everything exactly according to the checklist.
Seriously fantastic book and it's a quick read. Definitely recommended.
It's written by a surgeon who was involved in helping promote the use of checklists in healthcare. A lot of the book is about looking at their use in other places like aviation and construction and realizing why they work and how they can help in other places. The book spends a lot of time on the idea that some fields have become so complex with so many pieces that it's impossible for any one person to be able to track it all in their head on the fly and the effect that has in "can't afford failure" industries.
A book about checklists sounds like it'd be dreadfully dry and boring but the author is a solid writer and the book is full of a ton of really interesting vignettes -- I find people tend to fly through it. I first read it probably 10 years ago and it's one of those books that has really stuck with me since.
A lot of times these super professional responses are from having practiced emergency procedures until the checklist may as well be tattooed on the back of their eyes.
