The only 5' diameter spherical metal tanks that I know of on the shuttle are the LH2 and LOX dewars. The other tanks in the midbody are smaller.

I wonder if the crew module made it intact (being roughly spherical).

Gawd, I wonder what happened to the SpaceLab...

We need to establish video standards for capture and posting of images. "Timesink" had an image of a piece of debris that looks like part of the Lab module. It's charred and looks to be about 5 feet across.

It's definitely a piece of the lab module.
FNC had a video tape from a helicopter...it's about that size. Could also be a part of the payload bay door, but it doesn't look like that.

It's part of spacelab.

Looks like the cargo bay contents may have landed in one area around Nagodotches.

The rest of the wings and V-stab probably have more lift and go farther.
