Sickening.
These ships are bigger than the carriers most other countries have.
Social engineering gone out of control is what has caused this shameful disaster and will cause others if it is not ended and reversed. Forget that, it won’t happen.
Actually, it’s more likely that the contractors/shipyard workers will have been at fault and the fact that the ship was torn up with systems completely shut down for the refit will have been the cause of not being able to fight the fire in the early hours.
