Also, may be, the fact that controllers were scared after IL exercises over their shed, when they swore when on the second attempt the IL missed the runway, ended up to the left side of it. Following the first IL attempt when it also missed the runway but on the right side of it. Poles who were on the ground said IL's wing was 4-5 metres from the runway when it turned away off sharply when it missed the runway the first time.
Like, that the controllers knew, after IL's attempts, that it is not working out that morning, and still didn't prohibit the President's plane to attempt doing the same.
