"He's still at it, poor fellow. Seems to be under some delusion that he's in charge of the rescue."
— Allington Bridge Controller

"Day of Disaster" is the sixth episode of Thunderbirds Season 1, originally broadcast on 4th November 1965. It was the fifteenth episode produced.


A severe electrical storm weakens the Allington Suspension Bridge, causing it to collapse when the Martian Space Probe convoy travels over. Two technicians become trapped aboard the nosecone at the bottom of the river. International Rescue must free them from the MSP's when its impact with the riverbed starts the automatic onboard launch system.
