What is the Biggest Mistake You’ve Made in Infinite Flight?

Hey Infinite Flight,
I want to know what the biggest Infinite Flight mistake you’ve made. I’ll give an example below:

I was landing in Honolulu in the A330neo, after a pleasant flight in from Seattle. The weather was perfect, I had the flaps, trim, and everything set up for landing.

I was in the flare for touchdown, at the perfect speed, when I realized: my landing gear wasn’t down! Luckily, I could go full power to go around, and ended up buttering after another approach, but still.
