The Transportation Safety Board says the Swissair recovery operation is complete. The plane crashed off Nova Scotia's south shore just over a year ago, killing all 229 people on-board.

This week a suction dredge was used to recover the last ten per cent of the aircraft.

Jim Harris is with the safety board. He says the last of the wreckage of flight 111 has been delivered to a containment pond in Sheet Harbour, on the province's eastern shore.

Harris says it will probably take four-to-six weeks to sort through the debris. Once it's cleaned up, it'll be sent to investigators in Shearwater.

The precise cause of the crash has not been determined.
