That's pretty accurate. I won't say which company I work for but I work on control systems and write software for safety critical systems. It's usually C or Ada

That's pretty accurate. I won't say which company I work for but I work on control systems and write software for safety critical systems. It's usually C or Ada, like someone else mentioned and there's always two instances (if not more) running in parallel, talking to each other to make the right decision all in real time. A lot of the technology is 'outdated' compared to other industries, but that's because of the difficulties in qualifying new tools and systems.
