Air France’s emergency slides failed, investigators say

TWO emergency slides on the Air France jet that crashed last week in Toronto malfunctioned, investigators said as they pored over tire marks to determine why the plane skidded off the end of a runway at Canada’s busiest airport.

The Airbus A340 failed to stop after touching down during a severe thunderstorm on Tuesday, plunging into a ravine and burning to a charred and twisted hulk. All 309 people on board survived.

Investigators are studying data from the two black boxes - flight data and cockpit voice recorders - plucked from the dismembered plane, and are nearly finished combing through the wreckage.
