Can confirm. I worked as Airbus' tier 1 supplier and they were even accompanying us to manage our own supplier, which in hind-sight, ensured that things like this didn't happen.
In essence, did Airbus help advise what sorts of corners could/couldn’t be cut?
Supply chain management is incredibly challenging and it's interesting to see one school of thought moving away to vertical integration as an alternative solution and another doing just as well with suppliers (Airbus, Apple, ASML, etc).
