jack jacobs and former nbc aviation correspondent bob hager who we always welcome back in situations like this. thank you to you both for being here. let s talk about the protocol, bob. is there a protocol set for an international incident of this sort? usually, any formal investigation, it s the country involved. but in other cases such as the soviet downing of the korean airliner back in the early 1880s, or 1980s, and when we shot down the iranian air bus. the international civil aviation organization, a u.n. function, headquartered in montreal. i wonder if whether that s what will happen here. if i m not mistaken, i read that the russians, they held on to the black boxeses for a decade before turning it over.
