KC 777 There are far better sources out there that are more current than that one you have chosen to use You might find some in the Boeing KC 767 page As written your item implies it is still being activley considered which it is not Boeing went with the KC 767 earlier this year Sure it s still a possibility for a future order but that is just speculation at this point Incidently the story you cite doesn t say it would take two years to convert the KC 777 but three but I wouldn t know that as I didn t read the story
