(CNN)  -- A single-engine plane crashed Saturday outside a bank in Oklahoma City, Oklahoma, seriously injuring the five people on board, authorities said. A damaged airplane lies on the ground Saturday next to a busy road in Oklahoma City, Oklahoma. The pilot reported engine problems shortly after leaving the city's Wiley Post Airport, about a mile away from the crash site, at midmorning, said Lynn Lunsford, spokesman for the Federal Aviation Administration. The plane hit two trees as it came down, and video showed the damaged Beechcraft Bonanza resting on the grass near a busy thoroughfare in the northwest section of the city.
