They have, of course, failed to spot most of the asteroids that have whizzed by close until 3 days after the event.

And you've gotta wonder, if they didn't spot so many of them coming, how many did really they spot going? I'd be willing to bet they completely missed many, either coming or going.

If today's mapping programs have any great value, imo, it'll be to spark interest in programs that someday can actually do something to prevent collisions.

The SAC ICBM radar spots everything bigger than a grain of sand between here and the moon. Not that SAC can do anything yet about incoming ICBMs either.
