Air France crash: Jet fell for three and a half minutes

The Air France jet which crashed into the Atlantic in 2009 fell for three and a half minutes before hitting the ocean, French investigators have said.

The investigators say the crew had struggled with contradictory speed readings before the plane stalled and fell.

All 228 people on board were killed in the disaster, which is only now being pieced together following the recovery of the plane's flight data recorders.
