( CNN ) -- One of the two people killed when a corporate jet crashed into a row of homes in northern Indiana Sunday was a former University of Oklahoma quarterback who helped the school win two national championships in the 1970s , a school official confirmed Monday . Steven Davis , the 60-year-old former quarterback , and Wesley Caves , 58 , both of Tulsa , Oklahoma , were killed in the crash that also injured three other people in South Bend , said Randy Magdalinski , coroner of St. Joseph County , Indiana . Davis ' former Oklahoma coach , Barry Switzer , said Davis was n't a highly-regarded recruit , but excelled when he won a starting job . `` He went on to post a 32-1-1 record and help us win two national championships , '' Switzer said . `` Steve was surrounded by great talent on those teams , but he was truly an exceptional leader . I was proud of him . The entire state of Oklahoma was proud of him . We still are . '' OU athletic director Joe Castiglione said , `` We extend our sympathies to Steve 's family and others whose lives he touched . He was a great champion and someone who set a wonderful example for others . We will miss him very much . '' The Hawker Beechcraft 390 that Davis and Caves were on slammed into a South Bend neighborhood , damaging three single-story homes . Davis and Caves died on impact . Two other people aboard were injured , as was one person on the ground , Assistant Fire Chief John Corthier said late Sunday . The plane was sheared in half -- its nose poking through the front window of a shattered home . It was attempting to circle back to the city 's regional airport after a failed landing attempt . Moments earlier , the plane 's pilot had radioed for help , CNN affiliate WNDU-TV reported . He was experiencing problems with the technical equipment , he said . The plane was almost on its back and was `` spiraling down , '' resident Theresa Futa told WNDU . `` I 've never seen anything like that before in my life ever . '' A representative of the National Transportation Safety Board arrived late Sunday to investigate the crash . The plane left Tulsa , Oklahoma on Sunday afternoon , and was scheduled to land at South Bend Regional Airport about 80 minutes later at 4:20 p.m . ET , WNDU reported . The troubled aircraft startled Shelby Ramirez , who was driving in the area . `` I happened to see the shadow and I said 'Oh my God . I 've never seen a plane that low , ' '' Ramirez said . `` And I would say if it was 3 feet above the top of the car it was something . It could have dropped on us .
