Cruising crashes 'rare'
That the flight appeared to get into trouble as it was at cruising height strikes Forbes contributor Dan Reed as unusual. He writes that the "cruise" phase of the flight, i.e. altitudes above 30,000ft (9,100m), is one of the safest, with crashes far more likely during takeoff. What caused the flight to crash is not yet known, but owners Lufthansa are assuming it was an accident.

Cruising crashes 'rare'
That the flight appeared to get into trouble as it was at cruising height strikes Forbes contributor Dan Reed as unusual. He writes that the "cruise" phase of the flight, i.e. altitudes above 30,000ft (9,100m), is one of the safest, with crashes far more likely during takeoff. What caused the flight to crash is not yet known, but owners Lufthansa are assuming it was an accident.
