The pilot of the light aircraft that crashed into the 109-story China Zun (CITIC Tower) building about a week ago, the tallest building in Beijing, China, left a suicide note beforehand. Local authorities in China reported that the pilot wrote that he wanted to 'end his life' and that he had long suffered from insomnia and anxiety. It was also reported that 'in his diary, he repeatedly mentioned his desire to end his life.'
