Cell phone video shows the moments in the plane after that blache. The plane just left mogadishu on its way to djibouti before it reporter if it walks like a bomb and talks like a bomb, its probably a bomb.

Of course, we saw a hole in the plane and the first thing you worry about is, you know, can we really make it .
