IATA reported that 3.3 billion people flew in 2014 and projected that this number would increase to 3.5 billion on more than 50,000 routes in 2015.
Everyday it means that over 8 million people are in the sky on more than 100,000 flights. There are more than just people moving through the sky, as pilots transported 50 million tons of cargo
Transporting people and good resulted in a $2.4 trillion international economic footprint that supported 58 million jobs globally.
In 2014 there was only one major accident for every 4.4 million flights.
Accidents happen to stupid people.
If it isn't broken, don't fix it.
If it hasn't been a problem before, then it isn't a problem.
You have been sufficiently trained.
Safety is our top priority.
Accidents are impossible to predict.
Weather is a leading cause of accidents.
There is often a single cause behind an accident.
Accidents are "Acts of God".
Aviation professionals can let other things affect their concentration, such as checking personal text messages during a preflight check.
Someone may take a shortcut. When we do this, we are not giving our personal best and we risk missing key information and skipping items that may not seem important now but that could prove critical in a few months.
Operating Outside One's Training
Accidents can occur when we find ourselves doing something outside what we are trained to do. We often know that it is something we have not been trained to do and make a conscious decision to do it anyway.
It is easy to tune out warning signs when it is something that frequently occurs and which have not resulted in problems in the past. The problem is that the context may be different today, and therefore today may be the day that the warning applies.
Ignoring your Instinct
That expression may not sound very scientific, but it is essentially means that something does not feel right. Professionals should not feel uncomfortable when they are doing a task. If something does not feel right, it may be our protective instinct kicking in and recognizing that an unresolved discrepancy or problem is lurking in the background, ready to ruin your whole day.
