At least Thunderbird 4 is back this week. Albeit a new one, rather than "gluing" it back together, like the last time it was destroyed.
Wasn't the only thing back.
Thing the Zero-X design was taken from the ship that went to Mars in Thunderbirds Are Go and they've borrowed from the Space:1999 sound effects library again

And there's the fun of stock footage - TB4 is sitting in the launch area where TB's 1 & 3 are yet somehow gets into the Pod to launch with TB2.
