I remember that being process control chips that actually led to some pipeline explosions.
Explosions, wrong alloys, wrong processes. Fortunately the Russians were not actually very good at arcane stuff like chemical engineering and analysis but relied on stolen literature without the training background to properly use the material. Unfortunately this country is losing its engineering edge because we no longer train 90% of the world’s engineers or retain 90% of the foreigners we train. We are a “service” economy now, after all.
