Could be. If you look real close a soild piece comes out beneath the wing (very faint).

It took me several views before I caught that solid piece coming out the bottom. In other words it looks a bit like the solid piece came in from the top, glanced off the wing and continued straight down, while the vapor spray was ejected out at an angle off to one side.

Then again the vapor may have been the water from the ice and the hard object coming out the bottom may have been a tile.

It's a shame that the little camera that was a novelty a couple of flights ago wasn't installed. It was attached to the fuel tank looking down at the shuttle.

I think I see on the video where the ice hits the top edge of the wing...and then something falls straight down under the wing, its very faint like you say, then comes the spray. Good eye Mark
