Any distance this aircraft covered before that date — and for an airframe several years old that is most of its life — is not in this number, and we do not know it.
Each leg is computed from the shortest spherical distance between two recorded positions, not from a straight line from origin to destination; so turns, holding and rerouting are counted too, but wherever our coverage broke the smallest possible distance was assumed. For that reason the number above is a floor on the distance, not an exact measure of it.
Flights whose aircraft registration we did not recognise are attributed to no airframe and are not in this number. A flight whose origin or destination we do not know, by contrast, is counted, because what is measured is the flight track, not the airport pair.
