> Airbus has deeply integrated R&D and manufacturing hubs where the R&D engineers and scientists can just walk a few minutes and they will be inside the factory halls manufacturing the parts they designs.

This is not true. Airbus has a history of competition between French and Germany parts. The assembly plants are spread in France, Germany, UK, Spain, Italy. No such things as deeply integrated R&D and manufacturing hubs.

Boeing crisis makes Airbus look better. Airbus itself isn’t renown for efficiency.
