So far, Polish authorities have questioned 70 witnesses of the April 10 Tupolev 154 crash that killed 96 including Polish President Lech Kaczynski and his wife. The black box so far provides no clues, but they are anticipating the possible causes to be technical failure, human error on the part of the crew, ground crew, or third parties.
Sunday 10:30 a.m. Sunday at St. Maximillan Kolbe Church Poles will be holding a memorial for the crash victims. The Polish American Congress says people can sign a condolence book before the service, and it will be sent to the people of Poland.
