That would be Fireball XL5....different show, same writer/director/producer (Gerry Anderson) as with Thunderbirds. I used to get up at 6 AM every Saturday to watch these back in the late 60's when they came over to the US. Seen today the shows are pretty cheesy but back then (and at age 6-7) these were awesome shows...I can't wait for the movie.

here's a computer rendering of T-Bird 2 (my favorite, BTW) and Firebird XL-5...
