(1st row L-R) Late Polish President Lech Kaczynski's daughter Marta, grand-daughter Ewa, her husband Marcin Dubieniecki, twin brother Jaroslaw Kaczynski, attend the procession with remains of late Polish President Lech Kaczynski and his wife Maria from the Gothic Basilica of Our Lady for Wawel castle where they will be buried on April 18, 2010 in Krakow. Tens of thousands of grieving Poles packed Krakow Sunday for the burial of President Lech Kaczynski and his wife alongside ancient kings and heroes, though Europe's air travel crisis kept many world leaders away.
