"According to him [J Kaczynski] the fact that Blasik and Kazan were in the cockpit cannot be taken as proof of pressure being put on the pilots. According to Kaczynski such behaviour (non crew in the pilot's cabin) was something normal (i.e. usual, typical of these flights). I am stating this as a former Prime Minister who has travelled in this way tens of, perhaps even over a hundred times".
in other words: no pressure, as the crew were used to non-sterile cockpit. Doesn't make things look better?
