when they were told the pilot wasn't feeling well and one passenger said he knew it was a serious situation. we don't know the official cause of death. that's still unclear but we do know that co-pilot took over and because there is a two-person in the cockpit rule, it was a flight attendant who was in the cockpit when that co-pilot safely landed the plane with 147 passengers. >> what happened when the plane was on the ground? >> when the plane was on the ground ambulance met the aircraft and first responders boarded and the captain was pronounced dead right there in the cockpit. passengers say that they had to wait for the pilot's body to be removed from the plane. terribly sad story but really does under score why it so critical for two pilots to be in the cockpit, one is always prepared to take over for whatever reason. the other cannot fly the plane,
