In view of your observations, budge, I just viewed my Ice Debris Team magnified view video of ONE thing coming off the ET, forward of the nose, traveling down to the nose, then disappearing, the splatting at the 'crotch' of the wing, then spreading and leaving near the center rear of the orbiter.

The other video (no wing bottom, side view only) shows the BLOCK coming off, circling around, breaking into 2 blocks, 1 of which disappears, the other of which splats (cant see where) then debris sprays away from ship toward flames of the solid booster.

Two pieces, or perhaps two bounces of one block?

Does anyone have any idea what those three or four LARGE round
objects they've been showing of the recovered materials are?

Something from the cargo bay? Engine parts?
