洲际导弹发射时是航空管控了吗？

so what's your assessment of this unusual icbm launch into the pacific ocean and do you think this is a blow blocative action and and especially do you think they want to send a message to the us you know we monitored the icbm test to liz's question you know again we did receive some advanced notification of this icbm test and we believe that that was a good thing that was a step in the right direction and it does lead to preventing any misperception or miscalculation。
