There was a really good Thunderbirds game for its time on the inferior Sinclair ZX Spectrum 48k. I was amazed all those years ago by its puzzle gameplay design. You can play it here.

Edit : to set up controls since it's not noted on that page, you'll need to press R ( Redefine keys! ) and that'll get you started!

How to play : you swap between thunderbird 1 and 2 each ship by pressing spacebar ( default ) or whatever you configured it to. You'll notice the ship selected in the bottom left corner of the screen.
