That's a fantastic picture.
I've worked on some interesting software with lives on the line as well and the amount of test code absolutely dwarfed the functional part. I wonder whether at the time of the effort you linked that was already common practice and if it was what the fraction of that code was tests.
Assuming she's 1.65 meters tall and 66 lines per page (quite common back then), at 0.2 mm thickness per page that's 8K pages times 66 lines / page is ~550K lines. Pretty impressive!
