        • 36: Big Dig
          A series of concrete ceiling tiles in a tunnel portal collapsed on a moving car killing the passenger in downtown Boston in 2006. The selection of the epoxy used in the ceiling tile anchors was unusual and a failure to heed the warning signs were at odds on a huge project under pressure to deliver when already twice over time and five times over budget.

                    SpaceX and Elon Musk have been accelerating a project to provide high-speed, low latency broadband internet around the world via Satellites and are calling it StarLink. Radek joins John to deep dive into what StarLink is trying to accomplish, why it's a such a different approach to the problem and why it might actually succeed where others have failed.

                                                        One Friday morning in 1966 in a small town in Wales a mining spoils waste tip let go with a river of liquified rubble destroying buildings and a school. Killing 144 people, mostly children in their classrooms. The mechanics of how this happened are simple. The ignorance and economics of why this happened boggles the mind.
                                                        With John Chidgey.
