Thunderbirds Are GO (1966)

In the second half of the 21st century, the pioneering spacecraft Zero-X embarks on an unprecedented manned journey to Mars. However, the voyage is abruptly hindered by perilous technical glitches, forcing the crew to abort their mission and eject from the craft. The Zero-X plummets back to Earth, disappearing beneath the ocean's surface in a dramatic crash. Two years later, the Space Exploration Center unveils a revamped Zero-X, ready to attempt the daring Mars mission once again. In the wake of discoveries indicating sabotage on the first mission, they enlist the assistance of the Thunderbirds, a band of courageous ex-astronauts led by Jeff Tracy and his four sons - Scott, Virgil, Alan, and Gordon - each piloting their unique Thunderbird aircraft. Alongside them on Earth is the captivating Lady Penelope Creighton-Ward, stationed in the mobile command center, Fab1. The Thunderbirds are tasked with not only thwarting potential sabotage but also handling any unexpected technical predicaments that could jeopardize the mission. Amidst these high-stakes circumstances, Alan Tracy wrestles with feelings of under-appreciation, a struggle that culminates in a crucial life-or-death mission for himself and the Zero-X crew. The second Zero-X traverses the vastness of space, successfully reaching Mars, only to encounter a series of unforeseen dangers. These crises prompt a distress call back to Earth, triggering another pulsating response from the Thunderbirds. Once again, the call rings out: "Thunderbirds are GO!" As they race against time, the Thunderbirds must prove their worth, navigate deadly complications, and ensure the safe return of Zero-X to Earth. This thrilling saga of space exploration, sabotage, and bravery is a gripping journey that keeps the viewers on the edge of their seats from lift-off to touchdown.
