Krupski acquired his degree in history at the Lublin Catholic University in 1975. While there he became friends with other future opposition leaders, such as Piotr Jegliński and Bogdan Borusewicz (who in 2010 briefly served as President of Poland, after the death of Lech Kaczynski in the same plane crash in which Krupski died). Between  1977 and 1988 he was the chief editor of the independent, non-censored, underground journal Spotkania ("Meetings").

In a statement, the foreign ministry said the jet had been warned in Russian and English before it entered Turkish airspace on Friday.

It called the alleged violation "a type of irresponsible behaviour" and warned it would hold Russia "fully responsible" for all "undesirable grave consequences" which may follow, Russia Today reports.

Russian Defense Ministry spokesman, Maj. Gen. Igor Konashenkov, denied that there was any violation of Turkey's airspace and called the Turkish statements "unsubstantiated propaganda."
