Three separate investigations have been launched into yesterday's jetboat crash on the Shotover River. Five people - including the driver - were air-lifted to Lakes Hospital, where one still remains this morning. Two experts from the Transport Accident Investigation Commission are heading to Queenstown. The company - KJet - has also launched its own internal investigation. Dale Paterson lives near the river, heard a loud thump and saw a helicopter collect some of the passengers on Sunday morning.
