CommentReturning home. Again that one tracker shows a totally silly picture. All trackers appear to have data problems recently they all probably updated there databases and...well, messed up. I attribute this to poor database design and lack of domain knowledge. Most trackers were started by aviation enthusiasts which explains the less than ideal database design. When they took off they hired new staff and lost domain knowledge as the newly hired staff knows about importing data but not planes, while sticking to the old database.Operations
