What a surprise! It was never going to work - why doesn't someone give Boeing a new sheet of paper? They used the only one they had on the 777! All the rest of there range is 30+ years old re-hashed...
Now that has got your blood up, I hope that they do launch an efficient new design to replace the 767, as it will simply annihilate the weakpoint in the Airbus range, the A300/310. If they have the guts to do something new, it will be a fine product.
I am, however, insulted that they thought any of us really believed the 'Chronic Loser'...
