Each case counts once, on its first aircraft: by its defining event's phase from 2008, its first event's before 1982, and its first occurrence's from 1982 to 2007. Compare years within an era: a first occurrence (1982 to 2007) is often in flight, before the landing, so landings count lower then. Findings: https://openairdocs.org/ntsb-findings.md.
