Please notice that Open Glider Network and KTrax Logbook has requested low levels of requests to the Flightlog interface. The service has not been optimized for large batches. So please limit the live requests to e.g. 20 min intervals and if you request all historical information for a location put in some latency between each request to not stress the flightlog service.
