Falcon 4.0 is a video game and combat flight simulator that provides a realistic simulation of piloting an F-16 Fighting Falcon jet fighter. The FalconLog website provides Falcon 4.0 pilots with a place to upload their logbooks. The site stores the data online so that users can see their progress over time along with detailed statistics that go beyond what the simulator itself shows. The site supports multiple versions of Falcon 4.0, including Allied Force, Benchmarksim 4+ (BMS), Free Falcon, and Open Falcon. The logbook service can be accessed programmatically via SOAP API.
