Chaps1954..
Read up on the LR variant...only airborne tho yesterday.
We are experienced so obviously with aircraft ad nauseum that we want to think every potential pax has the same checklist in their head as ourselves.
Airbus & Boeing & the engine manufacturers are changing the thinking.
Try asking young people what is a wide body or single or double aisle? they do not even understand the question.
I remember the first Trans Atlantic twins arriving at LHR & in amazement really after growing up with four jets.
Now the market is very largely twin engine.
Times will change again for many...Nice plug for MAN but that highlights the case effectively as STN cannot by right expect a traditional operator with wide body service because it suits their own business model together with the prox of LHR/LGW but new concepts will provide STN & many others eventually with a 21st Century service.
