toss it to you. but both feel free to weigh in. if and when debris is found, who takes charge of the recovery and who has the best equipment to search for black boxes? steve first and then captain. >> well, it's very much a shared effort. at this point since the assumption is that the aircraft crashed in international waters, then the country of register which is malaysia would be in charge of the investigation. normally if an aircraft crashes on land or within the territorial waters of a country, the country where it occurs is in charge. so they will use a lot of -- typically they would use navy assets, this is a huge exercise in international cooperation, i note, and they will recover the wreckage. and i expect they would take to a fairly -- the closest place they could perhaps reasonably reassemble it or evaluate it.
