Looks like a short takeoff procedure. Early rotation, dropping the nose, building speed, then initiating a climb out. The goal is to get the wheels of the runway as quickly as they can. However, judging by the airport I would say its a drill of some sort. This has been discussed here before, simply do a check for it, I didn't read that other post, only saw it, so there might be more useful information there.
Ive seen this before, and am pretty certain it was taken at an airshow (I highly doubt that kind of manouever is permissable in normal usage at any airport on any airline). Cant shed any light on where and when tho.
That was taken at EDLW/DTM, Dortmund (Germany). I think its allready pretty much 6 or 8 years ago. Maybe less or maybe more, I dont know.
But nevertheless, this was I think the first Airbus for Eurowings (EWG/EW).
They presented this plane at their homeairport to the public. Plane was nearly empty and without pax of course.
Now this plane is flying for Germanwings.
Quoting EMBQA (Reply 13): That all depends on who you talk too as to what went wrong.
Im quite inclined to put my faith in the air accident investigators, the judge, the judiciary, the police, several airline pilots on this forum and multiple other people on this subject rather than a group of what essentially boils down to conspiracy nuts
