TOKYO (AP) — Transport officials and police have begun separate investigations at Tokyo’s Haneda Airport, a day after a large passenger plane and a Japanese coast guard aircraft collided on the runway and burst into flames, killing five people. The accident occurred Tuesday evening when the Japan Airlines flight JAL-516 plane landed on one of Haneda’s four runways after the coast guard aircraft — a Bombardier Dash-8 — had also entered, preparing to take off. Both sides said they received a go-ahead from aviation officials.
