A Second World War-era seaplane was forced to make an emergency landing on a city street after it reportedly experienced engine trouble mid-flight. Video from a camera mounted on the plane's wing shows the aircraft descending over Phoenix, Arizona, as it began to lose altitude on 12 April. The plane was reportedly flying without issues until the engine made a noise and smoke started filling the cockpit, Channel 12 News reports. After it touched down on an empty road, all three passengers exited the plane uninjured. A National Transportation Safety Board investigation into the incident is ongoing, but early findings suggest that the engine exhaust tailpipe separated from the manifold, the outlet reported. The passengers said that they gave their permission for the video to be used in future pilot training sessions.
