Thunderbirds were go this morning when one of the show's famous vehicles hit the Thames.
The Thunderbird 4 model, which measures 15ft and is made from fibre-glass, took a team of TV prop builders more than six weeks to build.
It was winched on to the river in east London before making its way past landmarks including The London Eye and the Palace of Westminster to mark the return of the show to TV.
Thunderbirds Are Go starts on ITV this Saturday with Oscar nominee Rosamund Pike as Lady Penelope with Kayvan Novak as Brains. David Graham is reprising his original role as the driver, Parker.
While the original series featured puppets, the new version will mix CGI animation with live action sets.
