One suggested explanation for the first point I've seen is that it was to limit damage to the surrounding areas in case of an uncontrolled collapse. I don't recall any evidence being presented for this claim though, and it doesn't strike me as particularly plausible, as it doesn't seem worth complicating the plan to such a degree for seemingly little benefit. The use of a missile rather than a plane has never made any sense to me - one unexpected photo, or even a plausible witness account, gives you a problem, despite there being an obvious way to avoid it. It also invites questions if the result is inconsistent with a plane crash in any way.
