CEO Bill Diamond.

From what we believe and observe and have understood about these, no, they were not in fact engineered, that they were natural objects.

Yes, it was disappointing.

It would have been amazing if it was a spacecraft, except I would then say, if you're a spacecraft, why the hell didn't you come by and take a closer look at us and maybe interact, you know? So if you came all that way, it'd be kind of a shame to miss us.
