In this Mistake of the Week, Mark Graban breaks down an incident involving an American Airlines A319 on final approach to Phoenix — captured on video with its landing gear still up. A cockpit alert sounded, the crew realized what was missing, and the pilots executed a safe go-around. Their explanation to air traffic control? A perfectly understated: “It wasn’t configured in the appropriate manner.”

Mark explores why these near-misses are less about individual oversight and more about systems built to detect — and correct — human error. From checklists to cockpit warnings to the decision to go around instead of pushing forward, this episode highlights why safety depends on catching mistakes early, not pretending they don't happen.
