"Thx .. do you have a link for that ? The only google refs I can find for such a DC9 crash in the Congo says it took place on TO not at altitude ?"
The very first video released claiming responsibility did not show an aircraft in flight, just a closeup of the plane burning on the ground. Lots of propaganda along with the pics.
I do not have a link to the video, but I do have a copy I could send you or post/send screenshots.
