And why did the French/British/German/Spanish/Italians develop the "Antonov rip-off"? Why? Because no government would touch the Antonov with a barge pole, let alone dare placing a multi billion pound order. However good the aircraft itself is, the ex Soviet manufacturers aren't as "reliable" in the business world I suspect
Because they wanted the An-70 (with some mods) first and then decided otherwise. the russians were very eager to mess up the program after ukraine decided on a pro-european course
(hence why the RAF uses AN-124s almost daily, but lets someone else operate them and hold the associated risks)
More likely because there arent any training courses offered to foreigners. antonovs own fleet is flown by people trained by the factory, and the other major operators are either russian (polet, volga-dnepr) or military (libya, russian airforce). Furthermore... there's a huge shortage of An-124s at the moment
