Pilots set the plane down in a storm, well past the normal touchdown area, for unclear reasons.
Thirty minutes later, the pilot set the plane down as gently as a china cup, and we bobbed over to a dock at the town of Craig.
On the 24 March outbound flight from Düsseldorf to Barcelona, Andreas Lubitz set the plane's altitude to 100ft five times while alone in the cockpit.
On 24 March 2015, Lubitz locked the captain of Germanwings flight 9525 out of the cockpit and deliberately set the plane on a collision course.
On the flight back to Düsseldorf, Lubitz again set the plane's autopilot to an altitude of 100ft and an eight-minute crash course over the French Alps.
There may be no evidence as to whether someone entered the cockpit or a pilot set the plane on another course of his own volition.
The European commission has set up a special taskforce to review cockpit safety rules after the Germanwings crash in which a co-pilot deliberately set the plane to crash in the French Alps, killing all 150 people on board.
As the New York Times revealed early on Thursday, French time, the voice recorder confirmed that Lubitz had locked the captain out of the flight deck and set the plane on its descent.
Both comments refer to the part that makes up about two thirds of the horizontal tail, and is used to set the plane's nose-up or nose-down attitude, for climbing, cruising or descending.
There was renewed praise at the hearing for the captain, Chesley B. Sullenberger III, and the first officer, Jeffrey B. Skiles, but the board found that it was "possible but unlikely" that pilots could set the plane down as the manufacturer had assumed.
