Figure 2.5 billion for the 20 767s (Aircraft manufacturers heavily discount their aircraft), 767 engines are practically being given away right now, so they can probably get 40 plus another 2-3 spares for around 200 million, another 5-10 million to gain an operating certificate. For 20 aircraft you're going to need a large spares department. Throw another 10-15 million on that. Pilot training another 5 million.
Just to get the planes on property is around a 2.7-2.8 billion dollar expense. That doesn't even factor in the infrastructure needed. Now I'm not saying they aren't going to do it. But to do it on the scale being discussed, we are talking about a massive cost undertaking. They have 14 Billion cash on hand so they can do it pretty easily. But will the shareholders accept another business undertaking while receiving little in return? I'm skeptical.
