On: Running Lisp in Production (2015)

If it runs on C++ now, it's been rewritten. Sabre predates C by many, many years and it almost predates Bjarne Stroustrup himself. I suspect a lot of it got moved to IBM assembly when they moved to S/360 mainframes in the early 70's. TPF is a descendant of that project.

I interviewed for a job working on Sabre in the late 80s, I was told it was written in C.

I suppose it no longer runs on IBM mainframes either. The original 360 port was in assembly and a dialect of PL/1.
