A few questions, if you don't mind.
1. The Chengappa article says that the first stage of the interceptor was liquid-fuelled. Does that rule out the Arrow theory?
2. It also says that a proximity fuse was used. So it's not a hit-to-kill vehicle as was believed on BR?
3. The photographs of the collision posted on the first thread on BR were taken after the debris of the impact re-entered the atmosphere? What about the spatial spread of the point of impact - does the point of converge maintain its integrity as the plume spreads? I ask because the Chengappa article mentions that the impact could not be observed visually or audibly due to the altitude of interception. So either the photographs were taken by satellite (in which case couldn't the collision also be observed real-time, contrary to what the article says?) or the photographs were taken from the ground after the debris re-entered the atmosphere, which leads to the question about the spatial integrity of the plumes.
