Q: Walentynowicz was an anti-communist dissident who worked with Solidarity founder Lech Walesa in the early 1980s to agitate against repressive communist rule. She was close to President Lech Kaczynski  also killed in the Saturday crash. Many others aboard the plane were also their ideological brethren.
 Walentynowicz was the most famous Solidarity activist aboard  an iconic figure more closely associated with the 1980 strikes than anyone save Walesa. She had sometimes been referred to as the Rosa Parks of Poland -- a nod to the American woman who was the public face of the American civil rights movement.
 A 51-year-old widow and crane operator in 1980  Walentynowicz was only five months away from retirement when her shipyard bosses fired her for producing and distributing a newspaper critical of the regime. She had handed some copies directly to her bosses.
 Her fellow workers were outraged at the injustice of her firing and agitated to have her reinstated  resistance that led to strikes and sit-ins at the Gdansk shipyard and in factories across the country.
 "I was the drop that caused the cup of bitterness to overflow " she once said  according to the weekly magazine Przekroj.
 "Anna had been at the center of the events that birthed Solidarity  and along with Lech Walesa she virtually personified the 1980 strikes in the public eye " writes author Shana Penn in "Solidarity's Secret: The Women Who Defeated Communism in Poland."
Walentynowicz were allowed to return to work.
 But it didn't take long for Walentynowicz and the other female activists to be sidelined by Walesa and the other male organizers.
 Walentynowicz was born August 13  1929  and was 10 years old when Nazi Germany and then the Soviet Union invaded and occupied the country. Her father was killed in the war and sheshe herself fell victim to a Nazi decree that prevented Poles from continuing their education after the fourth grade -- part of an effort by the Nazis to enslave Poles.
 She was initially attracted to communism and belonged to the party but eventually became disillusioned with their "lies and manipulation of the workers " Penn said. "She wasn't afraid to expose hypocrites."
 When Walentynowicz began her activism at the shipyard she was already widowed and had survived a near-fatal bout of cancer. Her unlikely survival from the illness left her with a sense that she had survived to carry out something worthwhile.
 "It took someone like her unafraid of authority to tackle the Communist authorities of the day " said Victor Ashe  a former U.S. ambassador to Poland who said he was honored to have the silver-haired Walentynowicz as a guest as his Warsaw residence on a number of occasions. "She was an amazing person who continued to express her views actively and directly."

Q: SAN FRANCISCO â Sayfullo Saipov  the 29-year-old suspect in Tuesday's deadly New York truck attack  earned money the way many gig economy works do. He drove for Uber.
But the fact that  Saipov  raised no flags for the ride-hailing company when it conducted its standard background check shows just how difficult it is to screen for potentially criminal behavior if there is no track record.
 Saipov  drove more than 1 400 trips for Uber in the past six months. Authorities continue to investigate the suspect  who came from Uzbekistan in 2010 and settled in Paterson  N.J. To date  his biggest offense seems to be from 2015  when he was cited by police for towing a trailer that was too long.
This undated photo provided by St. Charles County Department of Corrections via KMOV shows the Sayfullo Saipov.

The company's response to that incident was the same as its statement after  Saipov  rammed  his  rented truck into bicyclists  killing 8. An Uber representative said the company was "horrified" at the senseless act of violence as was cooperating with federal officials.
Uber said  Saipov  had been banned from the Uber app.
