This is a new problem with five photos of a Cessna Bird Dog N521ST previously labeled all UNKNOWN. They have now been edited as N521ST. Only one of the photos of N521ST uploaded to its Home Page. That photo has the ID shadow data. The other four do not show any shadow data. The other four did not upload to the N521ST Home Page. All copyright regenerations worked and all five photos show identical N numbers. Where are the other four? And how can they be moved to the N521ST page? The aircraft c/n 24584 shown on the aircraft tail correlates the aircraft to N521ST.
