Nothing like the AN124 whatsoever only that the upper deck is pressurised. The Boeing LCF is a SWINGTAIL product, the An124 is nose and tail loading but is Antonov isnt Swingtail.
B747LCF has 4x engines and is planned to be on the basis of a converted B744F. I understand Evergreen Aircraft Technoligies (Taiwan) are involved in this, i.e. the EVA group not EIA in the USA. Flight International reported this one or two weeks ago.
