What building a control tower taught us
Five lessons, paid in the field
Noise is not information. Agents who never read each other contradict each other. Captured is not delivered. Piloting blind is already losing. A rule that gets lost becomes a script.
The method that holds
Everything was measured, recorded, replayed. What could not be shown was flagged as such. That is what made the tower stand: an honest method, not a clever one.
