Hypothetical: What Doco Would You Film?

[Riksta]

This one's come about due to my addiction to engineering-type documentaries lately.

The Situation:
You are armed with a camera crew to film a documentary of any important historical event or disaster. You have a helicopter which can travel through time, to go back to any time and film something from times gone by.

Now, the helicopter is cloaked in some sort of mystical cloaking device - nobody in history will see it, will not be able to interact with it, and you are basically invisible and "not there" to anyone should you get out to do any filming. You are NOT able to change history at all, you are a "historical journalist" basically there to film the events for a documentary. No matter what you do, history will not be changed, we will now just have footage of the event. You are an observer - and there to find out exactly how things were done or what happened.

You CAN go back to events which have been captured on film, to get better footage, or a vantage point which was never able to be captured at the time.

Personally, off the top of my head, I would go back and film:
- The building of the pyramids
- The sinking of the Titanic
- The Wright Brothers' first flight

So what would you choose to go and film?
