Ultimate Crash Test: Countdown

Surprisingly little is known about the behavior of cars and drivers in uncontrolled, real-world accidents, despite rigorous testing in laboratory-controlled crashes. Now, a first-of-its-kind experiment aims to discover what really happens in a multi-vehicle pileup and how cars and driving could be made safer.
In the first episode of this two-part special, go behind the scenes as scientists make a series of high-stakes decisions to ensure the ambitious experiment goes off without a hitch. They only have one shot. The plan is for 8 drivers to drive 8 different cars by remote control at 70 mph down a hazardous straightaway. But how can they best represent real-world conditions to create a crash, especially when the drivers have no idea what's about to happen? How do they ensure that the remote drivers feel natural behind the wheel? And what is needed to fully capture every data-point possible? The intense preparation for the most ambitious crash test ever conducted culminates in the moment of truth as the cars barrel down an airport tarmac and collide in a massive, multi-vehicle pile-up.

Married at First Sight
Married at First Sight is an extreme social experiment that follows six brave singles yearning for a life-long partnership as they agree to a provocative proposal: getting legally married to a complete stranger the moment they first meet. Four specialists – sexologist, Dr. Logan Levkoff; psychologist, Dr. Joseph Cilona; sociologist, Dr. Pepper Schwartz; and spiritual advisor, Greg Epstein – create what they believe are three perfect couples, based on scientific matchmaking. The couples will not meet until they walk down the aisle and see each other face-to-face, for the first time, at the altar. Over the course of several weeks, episodes capture each couple's journey as they go from wedding, to honeymoon, to early nesting, to the daily struggle of working on their marriage. After several weeks together, each couple must make a decision: do they remain together or decide to divorce?
