> Except for all those listed in the article, such as a full engine replacement being hard to do at an airport not equipped for it, the engine being very hard to ship because it only fits on 2 plane models, with very few operators available, etc. Just because the repairs turned out to be quick doesn't mean that a full engine replacement wouldn't have been a significant multi-week undertaking. Hence why I said: "the logistical challenges if it had required an engine change are certainly real, though." It's still the case that all of those logistical challenges were considered when Air India decided to continue flying over Russia, it's not some kind of movie-plot "oh shit" moment when a diversion inevitably happens.
