It's weird.
Brand new aircraft, top engineering and latest technology.
Cracks in the correct places that are expected is one thing, especially after years of service.
But this is different. Very different. Airbus didn't expect them, and their official statement makes me think they are as surprised as the engineers seeing them for the first time.
I am sure they will all be grounded until thorough checks and tests has been done, together with necessary repairs... And this will cost Airbus more money and reputation.
There is nothing like a reliable and safe Boeing.
