'Mebbe' the Rooski plane actually did get airborne...who knows...none of us were there. But, 'real world' I just can't see that HULK ever getting airborne - even with all its engines at full throttle charging down a 20-mile-long runway at the end of which was a veeerytaaaaaaaaaaaaaall cliff.
(There's a diff twingst "flying" and "falling" remember...)
The first two "photos" are computer renditions. The next page's photos actually look real. Considering some of the past behemoths that they've made, this seem plausible.
All three 'photos' of the passenger version (which was never built) are renditions. The scale of the passenger version is larger if you compare it to the photo of the actual plane.
