A WOMAN in New Zealand has been charged with hijacking after she stabbed two pilots and threatened to blow up a small plane unless she was flown to Australia, police said. The 19-seat Jetstream J32 aircraft, operated by Air National for Air New Zealand, was flying from the southern provincial town of Blenheim to Christchurch when the mid-air drama unfolded, prompting the pilots to issue a mayday call. Christchurch police commander Superintendent Dave Cliff said the 33-year-old woman, a Blenheim resident originally from Somalia who was not immediately identified, claimed there were bombs aboard the aircraft.
