HALIFAX -- The Transportation Safety Board says investigators will spend the today documenting the site and sorting through the debris after an Air Canada flight crashed Sunday at Halifax's airport.

Mike Cunningham, the regional manager of air investigations, says a team of investigators are looking through debris from the point where the plane touched down at Halifax Stanfield International Airport to where it came to rest.

Cunningham says they have had a preliminary discussion with the flight crew and have also started interviewing passengers.

He says the flight data recorder and cockpit voice recorder have been sent to the board's engineering branch in Ottawa and will undergo a preliminary analysis.

Cunningham says it's not known yet when the wreckage will be removed from the runway, but he says it could be before the end of the week.

Cunningham says flight AC624 touched down about 335 metres short of the runway and hit an antenna array, where the A320 Airbus lost its landing gear, and then slid another 335 metres down the runway on its belly before coming to a stop.

The 133 passengers and five crew members all survived the crash, but some two dozen people were taken to hospital where most were treated and released from hospital.

Air Canada has said none of the injuries were considered life threatening.
