MINNEAPOLIS (AP) &045; The two Americans on board a helicopter that crashed in the Baltic Sea on Wednesday were a mother and daughter who went to Estonia for a wedding and boarded the helicopter so they could make their flight back home on time.

The aircraft was carrying 14 people. All aboard were believed killed.

The names of the victims were not released, but a family member said the Americans were Lydia Riis Hamburgen, 86, of Rochester, Minn., and her daughter, Mary Elizabeth Hamburgen, 46, of Rolling Hills Estates, Calif.

Arthur Hamburgen, 81, said he learned of the accident after the American Consulate in Tallinn, Estonia, called his son.

&uot;This sort of thing is very difficult, because you know, first of all, it’s two family members,&uot; said Arthur Hamburgen, of Rochester. &uot;And kids are supposed to outlive their parents.

&uot;My wife was ready to go,&uot; he said. He added it’s hard to lose a daughter, &uot;especially one like her. She bossed me around from the time she was 4 years old,&uot; he said lightheartedly.

Hamburgen said his daughter, a psychiatrist in southern California, was a loving, intelligent person who often organized neighborhood parties to get to know people.

She was married and had a 10-year-old son, Hamburgen said.

&uot;She was one of those gals who would do anything,&uot; Hamburgen said. &uot;She enjoyed skiing and gardening. She enjoyed her son. Even though she worked probably 60 hours a week, she always had time for her son.&uot;

&uot;She will be missed by so many people,&uot; he added.

Lydia Hamburgen, a native Estonian, had been invited to the overseas wedding by a fellow Estonian who also lives in Minnesota. Arthur Hamburgen said he didn’t make the trip, so his daughter volunteered to go.

&uot;That was just a great trip for them,&uot; Arthur Hamburgen said.

The U.S.-made Sikorsky S-76 helicopter, operated by Finnish firm Copterline, was on a commercial flight from Tallinn, the Estonian capital, to Helsinki, Finland, when it went down in strong winds about three miles off the coast, officials said.

Pictures from an unmanned underwater robot showed bodies inside the wreckage, rescue spokesman Aivar Murikse said. Divers would try to recover the bodies Thursday. The other people on board included the two pilots, who were Finns, six Finnish passengers and four Estonian passengers, said Kairi Leivo, a spokeswoman at the Estonian Embassy in Helsinki.

The cause of the crash was not immediately known.
