The pilots of Poland's presidential jet were flying too low and too fast and were poorly prepared, a Polish report into the 2010 crash that killed then head of state Lech Kaczynski said Friday. The crash report admitted most of the blame for the disaster in which all 96 passengers were killed lay with Poland, but it also listed a number of shortcomings by Russia where the plane crashed. The report said bad lighting at a Russian airport and errors by air traffic controllers also contributed to the 2010 air crash. Airport lighting in Smolensk, western Russia, was "defective and incomplete", the report said, adding that "the landing zone manager had given erroneous information to the plane's crew."
