CNN for one. CNN was blaming the attack on a possible guidance system malfunction into the middle of the afternoon on 9-11.
I also went back a few weeks later and watched a bunch of coverage from several networks on a website that archived that day's coverage from several news networks around the globe - don't recall seeing any such nonsense from CNN.
So, my real question is - ya got a cite? That would be an amazing thing to see, so I'd love to see it. I'm not saying it didn't happen, but that would be so against the grain of everything I heard that day that I am having trouble imagining it.
As an aside, as I was driving that day, many radio stations had ceded their programming to national coverage, and I heard quite a bit of CNN radio on that day.
