Optional track: how aircraft are inspected, maintained, and certified airworthy — the maintenance, repair, and overhaul (MRO) system that keeps every certified aircraft legally fit to fly.

An aircraft isn't simply inspected occasionally and trusted in between — it's maintained against a meticulously documented schedule, where every single task, no matter how small, has to be signed off by name before the aircraft can fly again. This optional track covers how Maintenance, Repair, and Overhaul (MRO) actually works, and why a single missing signature can ground an aircraft regardless of how it actually performs.
