There are folks practically GLEEFUL about the shootdowns.

Really? What has someone posted that indicates that they are GLEEFUL about the shootdowns? I might have missed where someone expressed joy, delight, happiness or any other "gleeful" emotion about the fact that we had three planes shot down.

Immediately chalking up an incident in one of the most complex air assaults ever attempted as "poor planning" is flat out ignorance. The level of coordination involved here is off the charts insane.

No doubt a massive amount of coordination is involved here - but I'm not sure why you think that negates the possibility, and perhaps the likelihood, that this resulted from poor planning. For example, the amount of engineering that goes into the structural design and planning of a modern skyscraper is off the charts insane - and if a skyscraper were to simply collapse, people would - correctly - point out that the collapse was due to "poor engineering."

Just because something is incredibly complex and requires off-the-charts planning doesn't mean that there can't be poor planning. You can have poor planning in complex scenarios and in simple scenarios. If you know what you're doing is insanely complicated, you know it's going to require insanely complicated planning - and if you don't do that planning to the level required, you will have planned poorly.
