2010 Polish Air Force Tu-154 crash

Poland's ruling Law and Justice unveils a new monument on the eighth anniversary of the disaster, which killed 96 including then-President Lech Kaczyński near Smolensk, Russia. Initial investigations primarily blamed errors on the flight crew but Poland is conducting a new investigation with a new report expected to claim Russian air traffic controllers purposely misled the jet about its location before it was destroyed in an explosion.
