Gladly! It's the second of these, "An investigation of the Therac-25 accidents" (1993) w/ DOI 10.1109/MC.1993.274940.

#1 is a later version that was an appendix to her book Safeware (which I have not read), and [3] is a nice second read that follows up on [2] many years later but isn't quite the relentless engineering detective story that makes the original so poignant.

This is the one :-). If I recall right, the journal scan had some additional diagrams some uploads have omitted, so while a PDF isn't the most ergonomic thing it's probably the safe bet.

I will take the opportunity to ask if there’s a good way to read PDFs using phone. How terrible it is!

Probably a Nobel to whoever solves this.

How ironic that, at the time, she was in a professorship endowed by Boeing.

Safeware is good. I read it back in the day. Several good failure analysis.

Thank you!
