Saunders Roe made another ‘white elephant’, three of them, in the forties.
“passengers were transported within an unprecedented level of comfort, being provided with luxurious first class accommodation, including a promenade, sizable galley, separate bathrooms for men and women, and individual cabins for passengers.”
So we have seen this before and will see it again.
The people in charge then thought they were right as did the people in Airbus and history has repeated itself yet again although the Saunders Roe Princess was a beautiful aeroplane unlike the A380!
