Subject: Cooper Files: Cooper-Part-41:049-051 Document: Annotated topographic maps: old/new flight course and terrain search areas near Ariel, Washington Id: Cooper-Part-41:049-051 Page: https://cooper.theunsolved.net/documents/Cooper-Part-41%3A049-051 What is wrong (title, date, type, which pages belong together, copies)? What does the scan show?
A person reads every report. Corrections are made by hand, to the data — titles, dates, names, which pages belong together — never to the scans, and they can take a while to appear.
