Well Foreign Worker at least you admit I could have a mindset, whether you like it or not, your post leaves me wondering if you have anything between the ears to generate a mind set?
I specifically said FLIGHT SAFETY , you note this as an after thought.
There is nothing about the term "unfortunate incident' that precludes the possibility of carelessness or irresposibility, simple basic English OK?
I see you have already attributed this incident to 'carelessness' - and on what do you base this assumption please? Ever heard of a brake system failure?
Suggest in future you read, think, read again and think again before you rush into print and start slagging people - you are obviously far from perfect.
