Re: Fatter Albert..
" their other problem for airports was the cost of all the gate modifications needed to handle them"
No different to what was needed back in the 1970s for B747s or the 1950s for B707s
B777s were introduced with folding wingtip options because of the gate issue. Nobody ever bought that option and gates were modified. B777X has the folding wingtips but I wonder how many will be de-optioned.
