During the hijacking Kavaja demanded and received another airplane which he intended to crash into the headquarters of the Yugoslav Communist Party in Belgrade.

[1] On June 20, 1979, Kavaja, already released on bail, took over the Boeing 727 shortly before it landed in Chicago from New York by threatening the pilots with a homemade bomb.

[1] He demanded the release of Stojilko Kajevich, a Serbian Orthodox priest and accomplice in the consul home bombing who remained in jail.

After arriving at Shannon Airport he planned to take control of the airplane and fly it to Belgrade where he would crash it into the headquarters of the Yugoslav Communist Party; however, after being persuaded by his lawyer, who was also on board, to not do so, he surrendered to the Irish authorities, who then turned him over to the Americans.

[3] Kavaja later claimed in numerous interviews with Serbian newspapers that Osama bin Laden stole his idea of crashing airplanes into tall buildings in the September 11, 2001, attacks.
