Skydiving plane crash kills nine in Sweden

Non of the paracutists got out of the plane, the crash didn't happen shortly after take off like it sayes in the BBC news article, the aircraft had climbed to 13500 feet and was put on hold before the drop as a commercial aircraft was landing first. According to the Flight Radar 24 data they had spent about 15 minutes above 10 000 feet when on the approach to the dropzone at the airport the plane suddenly "dropped out of the sky", part of a wing was gone when the ground videos was made, but inner part of them seems to be there. There where speculations that Mahindra had issued a check to the wingstuds inner attachement but as seen in the videos, the wings inner part is clearly there. What is hard to make out of the video is if the tail is still there, and at what part of the crash the wing separated, before or after they got into trouble. As it was full of skydivers I have a hope that the crashinvestigators Haverikommisionen will have plenty of videofootage from inside? It was a sad day :-(
