Leyvas' camera DID capture it!
Go to this YouTube version of the footage and watch it from 1:17 to 1:20 and compare that to Warren's photos.
Compare stills from Lehvas' video to Warren's first couple photos.
I think you missed the context of the question I was responding to. I was not contending that he never captured it at all.
That same image of the "detached plane" is obvious in Levyas' video and in Warren's stills -- AND THEY ALL LINE UP EXACTLY WITH THE FLIGHT PATH OF UPS 902.
