I still spoke to the poor guy on friday morning at Goma.. If i am not mistaken, he had just moved up to Goma from Lubumbashi after spending a while there and seemed relieved to be in a new place..
I also flew to Beni and back that day from Goma and the weather was not bad, just the usual clouds around the mountains at about 12000ft. I hate to say this but I think the one of the only ways that he could have flown into the 17000ft mountain is if he was not briefed on the routing that all the aircraft flying to Bunia/Beni take from Goma. That mountain is covered in cloud 90% of the time and friday was no different..
I did however hear from the aviation medicine doc at Goma (SA contingent working for UN), that the wreckage was spread over about 150mtr with no real visible impact point..
RIP guys, another sad loss to the aviation community
