If you believe in UFO's this might be a little unsetteling.  Russell Crowe says that he captured “several flying objects” flying over Sydney’s Royal Botanic Gardens in Australia.

He posted this up on YouTube and it seems to show flying objects streaking over the gardens. When he told the world about his video on Twitter, Russell Crowe wrote: “A friend and I set camera to capture fruit bats rising from Botanic Gardens. This was a big surprise.”

What do you think? Could it be a UFO, or is there a reasonable explanation?
