It must be something new - compared to what it was before. I mean, Polish delegations did come before, and several times. And OK, nobody was even once interested.
aerodrome - same old Beakons prehistorical
access side to the runway airport - as min it was the same on April 7th, just days before
ground control - same
Capt. Protasiuk - same

New components:
1. fog
2. likely - navigator
3. TU-154M - same, and did flew on the 7th April.
