Thunderbirds - Season 1 Episode 5 Edge of Impact
Thunderbirds are Go!
The Hood sabotages the Red Arrow aircraft programme. One of the planes crashes into the TV Tower in England during a brutal rain storm, and International Rescue is summoned to save the engineers inside the tower before it collapses; making their job trickier apart from the driving rain and winds at the site is that the Red Arrow's director, a long time friend of Jeff, is fired from the project and stays at Tracy Island, forcing the Tracys to draw him away and thus remain oblivious to International Rescue's existence.
