Greensburg/Trousdale tornado 4 miles wide?

[Paul Knightley]

Having more closely read the paper/article now I am even more amazed by the event. It does seem like the tornadic circulation, or a larger version of it, becomes the main storm updraught. I remember seeing footage of the May 3 OKC tornado, and how it seemed to stretch in one column way up into the sky (kind of merging with the wall cloud into one giant column).

And according to the Wichita Eagle article there's this quote: 'The Trousdale tornado may have been three miles wide from north to south at its zenith, Smith said -- though Umscheid said the elliptical shape of the damage path may have been the result of smaller tornadoes rotating around the main tornado."
I see the earlier link is dead, so here's another one that works that a pal who grow up in KS sent me:
