To mark International Thunderbirds Day on Sunday September 30th, streaming channel Twitch – which recently hosted marathons of Classic Doctor Who and Torchwood – will be airing every episode of the famed Gerry and Sylvia Anderson series – including the three new episodes made three years ago by the Thunderbirds 1965 team.

The 34-hour marathon will include the original 32 Thunderbirds episodes in high definition as well as the 3 new ones, kicking off with Introducing Thunderbirds at 3 pm UK time, (7 am PT and 10 am ET).
