Flights are derived from stored positions rather than declared by anyone, so this page reaches back exactly as far as retention and no further. Fixes that cannot be true are dropped one at a time, because real payloads emit occasional nonsense between good ones: an altitude outside −500 m to 45 km, a climb above 30 m/s or a fall above 100 m/s, or a sideways jump above 400 km/h against the previous surviving fix. No landing is predicted — that needs a wind model this program does not carry.
