ron bosch, thank you so much for speaking with us. explain how in your it unusual it is for a pilot to request a deviation from course which was the situation in this case? >> it's a not uncommon event. the aircraft was at its initial cruising altitude of 32,000 feet. the fact that it's in the tropics there where there's a lot of buildup of cloud and a lot of thunderstorms in that region. so the actual requesting a deviation from track is not uncommon. and as far as i understand, the pilot had indicated to air traffic control that the request for deviation was as a result of weather on the direct track. so not an unusual occurrence. but these are modern aircraft and they are fully equipped to deal with this type of weather. >> and ron take us through the emergency procedure that would have usually taken place on board the plane in such a situation? >> look, the aircraft is an a-320, a very modern aircraft, i believe this particular aircraft was only six years pomed a old. a very established airline winning sky track's aircraft carrier
