I believe what you are experiencing is related to my posting (
opensky-network.org/forum/data/695-missi...0am-gmt-onwards#1732). I.e. The Impala table: state_vectors_data4, which holds historic flight data, has not been refreshed since Saturday, 22 January 2022 10:00:00 GMT+00:00.
I also believe the Arrivals/Departures by Airport API has a dependency on the state_vectors_data4 table.
