(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.
Fire Department Deputy Chief Cecil Clay said the two men and three women on the plane were taken to hospitals. Lunsford said they suffered multiple injuries. Watch footage of the plane at the crash site »
The plane was headed to Enid, Oklahoma, about 100 miles north of Oklahoma City. The pilot tried to return to Wiley Post Airport after he recognized the engine trouble, Lunsford said.
"I heard what I thought was a Dumpster being unloaded in the complex," said Shaddy Ahmad, who manages the U-Haul business across the street from the bank.
He said emergency responders used special equipment to extricate the people from the plane, the top of which was peeled back.
"They were very lucky because this is a high-traffic area," Ahmad said. "You have the expressway, the bank and stores in the area. They were blessed to land how they did."
