From using the latest technology to unwrap a mummy and exploring beneath a site older than Stonehenge, viewers are invited to join DAILY PLANET co-hosts Ziya Tong and Dan Riskin on a whirlwind mission to solve the greatest mysteries of all time.

MAYDAY, Discovery’s 2018 Canadian Screen Award winner for Best Factual Series, returns for Season 18 uncovering the truth behind the most catastrophic aviation disasters. Airing Wednesdays at 9 p.m. ET / 6 p.m. PT, beginning May 2 the original Canadian series and Discovery primetime mainstay offers in-depth analysis, providing viewers a unique, behind-the-scenes look at the inner workings of aviation’s worst mid-air mishaps.
