Nice. Where did you found the information about the origin of the GDS? Was it difficult? Once I researched a lot and I didn't find too much.

I worked integrating software with GDS systems for some years, and I co-own a travel agency. I also built a tool to help travel agents, it translates some GDS codes to a human-readable format: www.easypnr.com

How did you find the information about how to interpret the black screen? Thank you for writing your article, I bookmarked it.

I have so many thoughts of this industry, and I also a personal theory of why we can't kill the command interface.
