Related to that is the fact that an accidental hit would most likely occur when a plane trying to land, and likely is low on fuel. If conditions are such that a pilot would be unaware of a 1000' building in front of him, the pilot isn't going to put himself in the air even remotely near such buildings unless he has no alternative. If a plane is on the ground during such conditions, it will stay there. If the plane is airborne and has enough fuel to either fly somewhere else where conditions might be better, or else circle at higher elevations while waiting for conditions to improve, the pilot would likely choose one of those options. Landing in dangerous conditions is generally only attempted for lack of a better alternative (although one may defer landing for awhile, "not landing" isn't really a choice).
Anyone involved with controlled demolition would have a different, well educated opinion.
Ask around, maybe you know someone in the industry, they're all saying, well, you know.
