One positive out of all this is that Boeing checking is working and finding things.

When extended periods of time pass without anything being noticed the two possibility are that indeed, all things are perfect, or, dodgy work is getting through un noticed.

But this is an internal matter and Boeing is onto it and rather unfair to place it on the World stage on the back of the problems the type has experienced.

With so much new technology in one go, there will be issues and in a way there could have been more as it was delving into the unknown.

Perhaps Boeings real mistake was to venture deep into the unknown while making firm promises of in service dates etc. They could not realistically promise such things simply because no one had been there before.

it’s often hard, sometimes disasterous to be first…DH Comet for example.

I think that chapter is closed.

This is something different, as said above cost cutting perhaps by others. Many types have these quality control issues once production is on the go (A.380 hairline wing cracks) and something that Boeing cannot be blamed for. Their responsibilty is to check that everything made for them is up to their standards.. They did, found problems and are acting upon them.

So this is a plus for Boeing, not a negative.
