No Laughing Matter:
No Laughing Matter is the antepenultimate episode of Volume 1 of the Terrahawks Big Finish series.
The episode title refers to Cy Splitter, the universe's funniest cyborg who gets kidnapped by Zelda.
Pardon the pun, this was quite funny due to how Splitter was employed by Zelda in her plans.
Also Ninestein showed a bit of humour when he says about things taking a funny turn!

Sale of the Galaxy:
Sale of the Galaxy is the first episode of the second volume of the Terrahawks Big Finish series.

Sale of the Galaxy is a spoof on the game show Sale of the Century.

This guest stars Nicholas Parsons.

As well as being a Gerry Anderson luminary, this has Parsons playing a spoof version of his real-life role as host of Sale of the Century, a role he performed in the UK in the 1970s and 1980s.

Quite a fun way to open Volume 2 with Ninestein and Zelda becoming contestants of the said game.
Fun on these foes playing against each other on this game.

Chain of Command:
Chain of Command is the fifth episode of Volume 2.

Interesting turn of events which got determined by the said chain of command.

This is in the midst of Zelda going missing.

Interesting the little mission that Kate and Mary when they are eventually met their by Ninestein.

Pretty good the said chain of command led to the climax of this episode and a very good one at that.
