The National Transportation Safety Board (NTSB) is investigating a crash involving a small cargo plane in Hawaii. The plane spiraled out of control and crashed into an abandoned building near the Honolulu airport, killing two young pilots in their 20s who were conducting a training flight. Eyewitnesses reported seeing the plane bank and turn back towards the airport before hearing a loud bang. The crash resulted in a plume of smoke and flames visible for miles. Fortunately, the building was abandoned, preventing further casualties. First responders quickly arrived at the scene, and officials praised the pilots for their efforts.
