Especially at 25 minutes in :-
[In] 2016 I think that we’re going to have to announce to the world that there’s a probe that comes very close to the Earth every 15 or 20 years. And we’ve been calling it an asteroid. It’s not an asteroid. But it actually in reality is an artificial probe. In other words, somebody else put it here.... I’m talking about BG1991. Roughly 30 meters in diameter, highly polished surface. Asteroids don’t have a highly polished surface. It took corrective course changes to avoid collision with another asteroid. That don’t happen. This one it did.
