Thunderbirds are Go!
Thunderbirds is a 1960s British science-fiction television series which was produced using a mixed method of marionette puppetry and scale-model special effects termed "Supermarionation". The series is set in the 21st century and follows the exploits of International Rescue, a secret organization formed to save people in mortal danger with the help of technologically advanced land, sea, air and space vehicles and equipment, launched from a hidden base on Tracy Island in the South Pacific Ocean.

While returning from a mission, Thunderbird 2 is seriously damaged when it comes under attack from a new, high-speed U.S. Navy strike vessel, the U.S.N. Sentinel. After an operation to move the Empire State Building disastrously ends in the tower's complete collapse, Jeff asks that Thunderbird 4 be transported onboard the same ship to the mouth of an underground river to reach a reporter and his cameraman who are trapped beneath the wreckage.
