uDb VS ufo_data

Copyright 1994-2002 Larry Hatch. Larry Hatch is deceased and permission has been obtained from his family. According to David Marler, Executive Director of the National UFO Historical Records Center, "The family has verbally given permission for the database to be used. If you need to speak with them, I have their contact info." Source Last but not least, I want to thank Isaac Koi for his restless efforts in collecting and sharing UFO data with the permission of their owners. This work could not have been possible without him, who managed to run the old software, perform an textual export of the data, and got the permission from Larry's nephew (the holder of Larry's Power of Attorney) to share Larry's work.

SS: The late Larry Hatch's UFO Database was nearly lost to time. Formally called the “UFO Database Mapping and Research Tool” (or just “U”). Over the years, there have been posts on this subreddit asking about it, such as here and here. However, dedicated researchers have obtained copies of the original DOS program, loaded it into emulator DOSBox, and programatically retrieved 18,123 of the 18,552 entries. The most recent of these researchers was Richard Geldreich Jr., who blogged about his efforts on Medium. Geldreich's work built on that of Adam Kehoe, who was given a copy of the database on floppy disks by researcher David Marler. Kehoe did a detailed blog writeup in 2021, now available on the Internet Archive. Geldreich and Kehoe alike built upon the "uDb" project by Jérôme Beau. Geldreich's code is likewise on GitHub.

I saw a post the other day about this project GitHub - richgel999/ufo_data: UFO/UAP event chronology creation tool . So what I did:
