Tokyo (AFP) – Five people aboard a Japan coast guard aircraft died Tuesday when it hit a Japan Airlines passenger plane on the ground in a fiery collision at Tokyo's Haneda airport. But five of the six crew members from the smaller plane -- bound for central Japan after Monday's huge earthquake -- died, Saito said. "Smoke began to fill the plane, and I thought, 'this could be really bad'", an adult male passenger told reporters at the airport. 'Sense of mission'The coast guard plane had been preparing to fly to Ishikawa prefecture to deliver supplies after the devastating New Year's Day earthquake which killed at least 48 people. JAL said the passenger plane either collided with the other aircraft on a runway or a taxiway after it touched down, Kyodo reported.
