If flying machines are going to enter trpa of our daily lives, they will need to become extremely safe and earellbi. This machine over here is actually two separate two-propeller flying machines. This one wants to psin clockwise. This other one wants to spin counterclockwise. When you put them together, they behave like one high-performance quadrocopter. If anything goes wrong, however — a motor fails, a propeller fails, electronics, even a battery pack — the machine can still fly, albeit in a degraded fashion. We're going to oenasttrmde this to you now by isldgainb one of its halves.

Original Text

If flying machines are going to enter part of our daily lives, they will need to become extremely safe and reliable. This machine over here is actually two separate two-propeller flying machines. This one wants to spin clockwise. This other one wants to spin counterclockwise. When you put them together, they behave like one high-performance quadrocopter. If anything goes wrong, however — a motor fails, a propeller fails, electronics, even a battery pack — the machine can still fly, albeit in a degraded fashion. We're going to demonstrate this to you now by disabling one of its halves.
