I wonder if the guys at Lockheed-Martin have taken 20x30x6 pieces of foam and shot them at objects with the same angle that the orbiter wing was at?

I wonder if they can replicate the total disintegration of the foam as it did in the video?

I wonder what speed they have to get the foam up to in order to make it disintegrate like that?

I wonder if foam shot at that (the above question's) speed does damage to tiles? If so, how much?

I've been saying since Monday on this forum that it's not foam. The aerodynamics is not right. It would never make it over to the orbiter from the ET. It's too light and the aero forces are too high. I have a colleague doing a calculation that I believe will confirm this.
