The aviation world isn't short of notes like this, but since my club has recently experienced two "it will never happen to me" incidents, I'm going to add to the pile.
Six months ago, while doing a few quick laps around the pattern for night currency, one of our pilots (with more than 10K flight hours) neglected to lower the gear and totaled our arrow. Our base is towered and I was on the board of the club, so I heard the tower tapes. The pain and resignation in his voice when he made the final call "I'm fine, but I'm embarrassed as hell and I've just ruined the airplane" made me realize that he'd already punished himself far more than we ever could.
Fast forward, we spend months looking for a new arrow and complete a deal on one. Someone flies it to base and lots of discussion takes place about getting the panel to look like it wasn't put together by the wright brothers. It went into the shop a few weeks ago and got upgraded to an aspen and a garmin 430W. One of our members picked it up a couple days ago and, I shit you not, wrecked it due to fuel exhaustion on take-off. Again, no injuries, so we're thankful for that, but two losses within six months due 100% to complacency. Out of curiosity I checked my Maule POH (don't have an Arrow one with me) and it has three fuel checks prior to take-off on the checklist. My recollection is that the Arrow is the same.
So, my goal isn't to have everyone pile on our two pilots. They screwed up, we know how they screwed up, they acknowledge they screwed up.
Just a reminder that the simple stuff wrecks airplanes.
I never got complacent flying 2 stroke ultralights for instance
