Wait, wait, wait...you're saying that because a missile has shot down a plane before in another country during a conflict, the United States military is firing cruise missiles without clearing civilian airspace?

Malaysia Airlines Flight 17 was shot down with a surface-to-air missile, a weapon intended specifically for targeting aircraft. A "cruise missile" by comparison is intended for terrestrial targets and has a minimum range of a few hundred miles. Should the missile come in contact with an aircraft during its initial launch phase, your warhead would basically come right back down on top of you - which is why they close the airspace.

This is reference to this incident that happened during peacetime in 2001 - not later incident during the conflict.

I'm not sure how that's related? Ukraine was a warzone at the time.

And still is at the time :(, just nobody cares anymore

this is a poor comparison

shh, those were aliens too, at least according to Russia.
