Nigerian man Aghogho Ajiyen from Delta state, builds Aircraft with local materials. Even without a University degree, he assembles these machines and make them to fly. He assembled his first aircraft in 1999 but didn’t succeed at it. He continued and got better with his next try. He said he does his research on how to assembly aircraft by himself and decided to put it to test.
He even installs a camera on them which he uses to survey his environment and has developed his own special fuel for his aircraft. Amazing.
