Here's Moscow Approach, have a listen and compare the controllers level of English to that of the pilots they're speaking to...
It is again mistake of pilotes.
1.Why did they go to Smolensk, knowing-a)air controller doesn't speak by English,
b)Smolensk airoport is so small.
If even they thought before starting that they can avoid these problems but why they couldn't take away from Smolensk? Why?
It is i think common Slav carelessness. but they carried so VIP persons and this carelessness couldn't take place. They have to check every small problem.
Really i think-it was real Vip person syndrom. And I was very much wondered that plane was in way when ceremonial already started... of course, it wasn't time to go to Minsk, Vitebsk and espessially to Moscow.
In Russia there is saying-''Will be hurry-will be funny for other people'. But it is not funny, unfortunatelly...
