Well, that article you remember (which I don't have) is likely to be an update to the article by Pierre Andriebet, Director of ATC software development Thomson-CSF/DSC (phone 33.1.4094.3214) entitled, "Cost Effectiveness of Using Ada in Air Traffic Control Systems", published in Ada: Experiences and Prospects, Proceedings of the Ada-Europe International Conference Dublin 12-14 June 1990 ed. Barry Lynch. FWIW, there is a table in that article showing that by the 4th ATC system (Pakistan), they achieved a 79% reusability ratio. I hope this helps.
