HONOLULU (AP) — Investigators are reviewing the records and the burned-out wreckage of the single-engine plane in Hawaii that went up in flames just after takeoff and then exploded as it hit the ground, killing the pilot, two instructors and two tandem jumpers. The pilot, two instructors and two tandem jumpers were killed when the plane believed to have been operated by SkyDive Kauai crashed Monday, firefighters said. The company is listed in state documents as a trade name for D&J Air Adventures, the registered owner of the Cessna 182H, according to Federal Aviation Administration records. Investigators reviewed the burned-out wreckage of the single-engine plane in a field just outside a regional airport on the island of Kauai.
