@老寓公，别把我的贴子断章取义，这是我的帖子的全文：
“对美国政客和媒体而言，确实让这个气球飞着的价值绝对大于打下来，但打下这个气球也确实是不容易，2万米已是战斗机的极限（F22的极限是10mile，即16000米），要飞到那个高度必须全速，如此高速飞行如果是用机枪打一个静止目标是非常难的，至少要在气球下方来回上下飞行扫射，即使打中了，气球也不会像玩具气球那样会爆炸，气球可能还会飞相当长的时间，而扫射的子弹落下来对地面人员和财产都是危害，用导弹打也不容易，因为导弹不是设计来打静止/漂浮物体的，一般来说，导弹会把气球当作浮云而忽略，除非气球正好在导弹的飞行路线上，而未击中目标and/or未爆炸的导弹落到地面上危害更大。”
这是yahoo上的文章：The problem, the former naval aviator said, is that missile systems, both surface-to-air and air-to-air missiles, "aren't designed to attack balloons because balloons don't look like the kind of valid targets that they were designed to attack," like enemy aircraft or missiles.
"They don't move like a cruise missile," Tannehill said of these kinds of balloons. "They look more like a cloud or chaff, and modern missiles are designed to ignore chaff,"
