7/24 starting-position score
Strongest documented signals: Elite institution pipeline, Frontier geography, Rare early tools.
Describes the starting position, not what the person later made of it.

Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Chesley Sullenberger's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Chesley Sullenberger's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Born in Denison, Texas to a middle-class family; his father was a descendant of Swiss-German immigrants. He grew up near an Air Force base, which sparked his interest in flying.
Not documented in reviewed sources.
Sullenberger's early advantage came from the elite Air Force Academy pipeline, which selected him for its cadet glider program and where he became an instructor pilot as a freshman. He had started flying at 16 and earned a glider license at 14, showing exceptional early aptitude (99th percentile academically, Mensa member at 11). The Academy provided world-class flight training and a direct path to becoming a fighter pilot. His family background is not well documented beyond being middle-class in Denison, Texas.
