a twa constaliation hits a united dc-7 over the grandcanyon with 128 deaths the crecord in 1956. the cause was the lack of safety features and radar over that part of the us and the fact that there are terms like 1000 on top which means they can fly any altitude 1000 above clouds which leads to breaking rules and colisions like this.
next time a dc-10 loses an engine literally.
