Looks like it's not just a scene from a CCTV camera and guesses:
Awantura przed Smolenskiem?
There's a witness, a junior officer of the Government Protection Bureau, (BOR, Biuro Ochrony Rzadu) who heard gen. Blasik sharply rebuke kpt. Protasiuk for his refusal to take off in absence of proper meteo data from Smolensk. Allegedly, he ordered kpt. Protasiuk to go to the cockpit and start preparations for take off, while the general himself reported the crew ready for the flight to the president.
