A little late for this one, but as your official Spanish translator, I thought I could add something.
First, yes, it looks like an equivalent of your Angel Flights (that was obvious, no need to Speak Spanish to say that, huh?).
Then the people on board. The news commentator lists the passengers after the crash, and they were a total of four including the pilot. BTW, no idea of how he evolved later, but by the time they released in the news, the pilot was alive.
She remarks a comment made by the pilot, so I guess reading the whole story we could find out that it had something to do with the accident. He says: "Quiet, don´t make me move the feet backwards. Don´t make me touch the pedals, did you hear me? At all" Not much idea of what he meant with that "move the feet backwards" and "(no)...touch the pedals", but anyway, it seems like she had her feet on them and seems to he already asked her before to stay away from the controls.
Watching them taxi, you can see her hand up; hearing her cry, you can say she was NERVOUS, so maybe she could have interferred with the controls at any time of the procces. As Supercubber says, he does nothing to fight the left wind, and I don´t think any pilot would leave the plane fly like that without at least trying to do something, at least moving the ailerons, the rudder... something. As he starts to get off the ground, the plane aligns with the wind, as it would do by itself if you were doing nothing to avoid it. Slightly aligned, but being displaced with the wind. It doesn´t make anything but flying like a kite until almost the end.
No idea of what happened by just watching a not exactly high quality video, but introducing the comments and the importance given to that pilot´s words, you can have another point to view it.
Of course, the heavy load, mostly placed on the back, could have put the CG out of the limits, no doubt about it, making the plane handle more or less as we can see. That´s what I´d have said if not influenced by the comment.
