I wrote recently, in another thread here, that Boeing relied for its manufactured titanium components on a Russian company , as did Airbus. I apologise - I got that partly wrong. Truth is that Boeing stopped relying on them in March but Airbus still do. Boeing stated that there were enough parts in stock to satisfy current demands. Sooner or later they will use all of this stock and, perhaps by then, they expect Russia to have fallen to the US planned Russian capitulation. Good luck with that.
