66 million years ago an asteroid crashed into the Gulf of Mexico. But how did a bad day in Mexico turn into a global annihilation, wiping out not just the dinosaurs all round the world, but also 75% of life on Earth?
Alice Roberts and Ben Garrod follow an expedition to drill into the crater to discover the truth of the worst day in the history of life on Earth.
