Two cities, two disasters, decades apart. This episode of Disaster Deja Vu opens with the deadliest tornado ever recorded, the 1989 Daulatpur-Saturia tornado in Bangladesh, and traces it back to an earlier deadly weather system that struck the same region in 1973, using archival photos and reenactment footage to show how the terrain and building materials made the area a repeat target. The film then moves to Calgary, Alberta, where a summer hailstorm dumps ice large enough to smash through windshields and roofs, tearing apart homes, businesses, and cars, and compares it to an earlier hailstorm that hit the city with similar force. CGI reconstructions sit alongside original footage and archival material to walk through wind speeds, storm formation, and the human toll in both places. The throughline is repetition: why the same cities keep getting hit by the same kind of catastrophe, and what that pattern means for how they rebuild.
