So the footage from my previous post was is not a new occurrence. zorgon; a member of AboveTopSecret.com mentions in the NASA UFO STS-120 External Fuel Tank thread that there is similar footage shot during the same maneuver of STS-115. As I previously posted, NASA uses handheld cams to capture this footage for analysis of the tank for damage. Once again it is a spiny like object, similar in colour to the previous crystalline structure seen on STS-120.
