( CNN ) -- The group of Hungarian teens and young adults had traveled to the United States to experience American culture during a three-week trip of hiking excursions , overnight retreats , home-stays and tourist stops . Now , the group will return home without two of its members , carrying memories of the tragic boating accident that took their lives . The bodies of Dora Schwendtner , 16 , and Szabolcs Prem , 20 , were recovered from the site of the boating accident in Philadelphia , Pennsylvania , on Friday and identified later in the day , according to authorities . The discoveries came two days after a tour boat the group was on collided with a barge in the Delaware River . Rescuers saved 35 people on the tour boat , popularly known as a duck boat , an amphibious vehicle that takes passengers on land and sea to major destinations on Philadelphia 's tourist track . Among those rescued were some of the Hungarians and their hosts from Marshallton United Methodist Church of West Chester , Pennsylvania . Schwendtner and Prem were missing for more than two days before their fate was confirmed . The 15 Hungarians arrived in the United States on July 2 on a cultural exchange program organized by Atlantic Bridge , a Netherlands-based group that describes itself as `` a Christian , international , cross-cultural team with a passion for young people . '' The team of Hungarian `` BridgeBuilders '' came from Mosonmagyarovar , a town in northwest Hungary known for its hot baths and large number of dentists , drawing Austrians from across the border in search of cheap dental work , according to Atlantic Bridge 's website . The leaders of Atlantic Bridge did not respond to e-mails for comment Friday night , but the group 's website provides a loose timeline of the youths ' travels . Representatives from Marshallton United Methodist Church did not return requests for comment Friday night . After the youths arrived in New York they spent the Fourth of July weekend visiting ground zero , Central Park and Chinatown , and celebrating the nation 's birthday with host families , Atlantic Bridge 's director , John Oostdyk , wrote on the organization 's website . On July 6 , they set out in five cars to West Chester , Pennsylvania , to meet their hosts from the Marshallton United Methodist Church for the next leg of their trip . Marshallton sent a youth group to Hungary through Atlantic Bridge in 2006 , and a team from Hungary first came in 2007 , the church said on its website . `` Together the two youth groups share in Christian fellowship and fun , while the visitors stay with host families , and enjoy tours to various cultural and historic places in their respective countries , '' a statement said . The next day , seven members of the church accompanied their Hungarian counterparts on a trip to Philadelphia , where they boarded the `` Ride the Ducks '' tour boat at Penn 's Landing . The boat had mechanical trouble and the engine shut down after a fire onboard , Lt. Frank Vanore of the Philadelphia Police Department said Wednesday . While the boat was waiting for help in the river , the barge hit it , Vanore said . The boat overturned and passengers were spilled into the river . `` When I saw the picture I realized how true it was when someone earlier said 'it is a miracle anyone survived this , ' `` Oostdyk said on Atlantic Bridge 's website . `` Ride the Ducks '' voluntarily shut down operations at all its locations across the country , and the NTSB is investigating the incident . `` Our thoughts and prayers are with our Philadelphia tour guests , crew members and their families . We are attending to their needs first , '' the company said on its website . After the passengers were brought to land , a count was taken and it was discovered that Schwendtner and Prem were missing , the church said . The group went back to Marshallton , where they were looked after by the Rev . Scott Widmer , the church 's pastor , and members of the congregation and community . `` The church is continuing to provide comfort , prayer , pastoral care and sanctuary for the spiritual needs of the youth groups in the midst of their shock and grief , '' Marshallton said on its website . The Hungarian youths are still in Pennsylvania , according to an employee in Atlantic Bridge 's Netherlands office , but it was unclear whether they would stay until their scheduled return on July 23 . On Wednesday , Oostdyk flew to the United States to be with the group . On Thursday , prayer vigils were held at two United Methodist churches in the region , drawing attendees from churches and communities throughout the area . `` It was a world of grief , but also a world of compassion and prayer and of gathering around the team of Hungarian students who had seen their summer of high expectations destroyed in a matter of minutes just 24 hours earlier , '' Oostdyk said .
Bodies of Dora Schwendtner , Szabolcs Prem , found near site of Pennsylvania boating accident . They were among 15 Hungarians on cultural exchange program with Pennsylvania church . They arrived in the United States July 2 to experience American culture . It is unclear if the rest of the group will stay until scheduled return date of July 23 .
