As with most accidents multiple things go wrong and pile up on one another until control is lost.
We may have controls and safe guards in place to handle each individual thing that could go wrong but when multiple events occur the controls for each event may not be able to control the sum of all the events at one time. Foreseeing an infinite combinations of individual events and having a planned reaction to whatever the combination of events is is the problem.
Probably no human endeavor other than the manned space program has received the "what if" scrutiny and back up to the back up to the back up redundancy more but it hasn't prevented several catastrophic events such as Apollo 13, the loss of two shuttles and the Apollo fire on the ground that killed 3 astronauts.
