The sky was clear, the reason for the rapid descent of the plane is not known yet. As Germanwings is a Lufthansa owned company, often the media just reports of a Lufthansa plane having crashed, and people who know that I work also on this type of aircraft started worrying.
The passengers on board and also the crew were mainly German and Spanish. My deep condolences to family members and friends of the victims of this accident - unbelievable that something like this happened in Europe. It feels like loosing family to me, being very connected to aviation, cockpit and cabin crews throughout the company.
