The Multi-National Forces web site has posted some pictures of the Vehicle Borne Improvised Explosive Device (VBIED) which detonated outside the Green Zone this morning. My one warning is that you should be prepared to wait if you click on the thumbnails, because the files appear to be quite large. Also, note the distortions in the first picture around the light poles. This distortion appears to be caused by the extreme heat--at approximately 9:30 am.
UPDATE: Lt. Naum, who is an Abrams tank commander, wrote to offer a kind correction to my post. "The heat distortion in that picture is from the exhaust of that big, beautiful monster in the background. Id recognize it anywhere, and can smell that sweet, sweet aroma right now. Mmmmmm. Tank fumes."
I have personally walked behind an Abrams tank a few times while they were running, and I can attest to the sensation of being hit by a wall of driven heat that feels like a full-body hair dryer set to singe.
