Some of you may consider this a bit heavy for a Saturday night. If it is, I apologise. I've been meaning to write about this all week, but my schedule never allowed it. This week marked the 40th anniversary of the Space Shuttle Challenger disaster. 28 Jan 1986. I'm afraid I remember it really well. I was 13, absolutely infatuated with anything to do with aviation and space, and my Mum burst into my room in the morning, woke me up and tells me that the Space Shuttle had exploded. I was absolutely shocked, and could only think of the teacher who was famously on board as a passenger, Christa McAuliffe. What would her students be going through right now? It was my first exposure to utter disbelief and sorrow. Years later, as an Air Force aircraft technician, our group studied the human factors behind this disaster. We quickly realised the investigation had made an uncommon theory quite suddenly very famous amongst investigators. “Normalisation of Deviance” Described by Columbia professor, Diane Vaughan, “Social normalisation of deviance means that people in a group get so used to doing something wrong that they don't see it as wrong anymore, even if it breaks their own safety rules Let me explain it another way. Imagine there is a road on your way to work that you always go a little bit faster than the speed limit. You never get caught, so every day you continue to exceed the speed limit on this bit of road, sometimes going dangerously fast. This is deviant behaviour. Your safety is at risk, but your everyday risk assessments allow you to think it’s ok. Until one day, the conditions aren’t ideal, you skid off the road and cause a terrible accident. That's Normalisation of Deviance. The engineers who built the solid rocket boosters for the Space Shuttle also knew there was a problem with their design. A primary O-ring sealing rocket fuel in one of the massive solid rocket boosters has had previous faults. The engineers all know about the fault. Due to contractual pressures, they continue to assess the risk of failure as low. On the day of Challenger launch, the conditions aren’t ideal. Unseasonal cold, icy weather hardens the o-ring, making it brittle. 73 seconds after launch, it fails, causes a leak in the SRB and explodes, destroying the entire Space Shuttle, killing 7 astronauts. That's Normalisation of Deviance.

I’ve got a special offer for all of you lifelong learners. How does FREE access to the Human Factors Kickstart course that is in my classroom sound? In order to make the best quality course, I need some users to test it for me, so I can improve it off your feedback. @David Ferris has had a look and provided some valuable information, which has been so useful. Thanks heaps mate. I truly appreciate it. So far, I have built two modules. 1. Introduction to Human Factors 2. How our Human Information Processing System works If you’re interested in learning and helping shape the rest of the course, reply with a YES and I’ll provide the access for you. Another benefit you can all get is the absolutely awesome Skool affiliate commission💰💰that Foundation Members get when they share the course with friends and colleagues. You’ll get 30% when they purchase, so the more people you tell, you get a little WIN! 💵 This is the same course that has made aviation the safest industry in town. Critical roles like Aircrew, Maintenance and Air Traffic Control have received Human Factors training as a staple foundation for years and years. It has recently been making its way into Healthcare with frontline feedback showing it has saves thousands of lives. Construction, mining and other High Reliability Organisations are using it more and more as well. I’ve seen Private Hospitals turn this training down based on its expense (it’s actually always been a fairly low cost course) while other Public hospitals have embraced it and measurably reduced accident injury rates. So reply with that YES and Ill open up the course for you…

G’day everyone! This week I’ve managed to get one and a half modules for the HF Kickstart course online. How do you feel about taking a look for me?

Have you ever wondered why preliminary accident investigations are concluded relatively quickly, whereas the final report often requires months or even years to complete? When an accident occurs, the first priority is to determine what happened. This part is relatively straightforward — with today’s technology, such as the Cockpit Voice Recorder (CVR) and Flight Data Recorder (FDR), along with other available evidence, investigators can usually establish the sequence of events quite quickly. However, uncovering why the accident happened is a far more complex and time-consuming process. This stage often involves a deep examination of human factors — psychological, physiological and organisational influences that may have contributed to the event. I’ll leave the discussion here for others to share their insights and elaborate on the specific factors that can play a role.

Dear Participants, The Kickstart course offers a valuable opportunity for both learners and facilitators to connect and build mutual understanding through effective communication. I encourage all of us to reflect not only on how we communicate with others, but also on how we are perceived in return. Communication is one of the most fascinating and relevant topics in human factors. Together, let’s explore two key questions: - How can we communicate more effectively? - What barriers might stand in the way of clear communication? I look forward to hearing your thoughts and insights.
