A modification to my report, so that it always shows YESTERDAY's flights:
SELECT DISTINCT
Aircraft.ModeS,
Flights.Callsign,
Flights.Route,
Aircraft.Registration,
Aircraft.AircraftTypeSmall,
Aircraft.Airline,
Flights.EndTime,
date('now','-1 day') AS FIELD_1,
substr(Aircraft.LastTime,1,4)||"-"||substr(Aircraft.LastTime,6,2)||"-"||substr(Aircraft.LastTime,9,2) AS FIELD_2
FROM
Aircraft
LEFT OUTER JOIN Flights ON (Aircraft.ModeS=Flights.ModeS)
WHERE
(FIELD_1 = FIELD_2)
ORDER BY
Aircraft.Registration,
Aircraft.ModeS
