Sectors are two-ended flight records held from 2020 onwards. Movements are one-ended Heathrow and Gatwick airport records — so a year showing movements only is expected, not missing data. Coverage varies by year; a sparse year reflects what was recorded at the time, not the whole of the aircraft's activity.
Recorded before 1990: 51 records across 5 years sightings

Heathrow and Gatwick movements reach back to 1955, but every year before 1990 is graded sightings: scattered movements were written down, not the year. A year here means this aircraft was recorded at least once, not how often it flew. What the early records are.
