>>>And who is going to provide documented evidence to these get rich quick lawyers to say that there is a fault with the cowlings or that a BA engineer failed to check that the locks were secure?
Not really needed, as the evidence is that the cowlings obviously were not latched correctly...
If BA don't have a suitable "process" for preventing this and so are putting lives in danger, then they need some "incentive" to make sure it is "safe".
Pay money to get it right, or pay damages if you couldn't be be bothered to make sure it is right and you get caught...
The cowlings were not latched safely - that may be a design fault, or "someone" didn't do this properly. But the walk around "should" have discovered this, so it may be a combination of 2 failings.
