so u actually believe them?
Why not go to them and ask for confirmation via a contract. Make them sign a contract saying that they will have those 6 planes ready by the time that the promise.
The same thing was promised a AAG in Sharjah. A friend of mine was that the planes actually came 2 years after they were promised. The students actually got fed up of asking for the latest news on the planes!
I for one do not trust a word they say anymore!
