Relative airspeed between ET and orbiter is in the order of 800-830kph at that point (sorry for being metric :). I don't know if this can be considered the impact speed, what with inertia of the piece vs. its presence in relation to that area and all, but it ought to be roughly about the magnitude. Couple hundred mph. >In how many frames does the debris appear? In the E-212 footage it appears in eight or nine frames, depending on how closely you look. Followed by ~2 frames where it is covered by the wing before the impact cloud first shows up. CU!
