Reused shot from Alpha Child
A real nuclear explosion: historic film from of the Baker test, 24 July 1946.
0 fatalities (128 dead in the alternative timeline plus Koenig and Carter).
Eagle 1 (Alan: internal number is 9); 2 (in flight 1); 6 (Koenig, unarmed); others. In the end none are destroyed.
Unnamed planet. Note that one shot shows two suns in the sky.
Unnamed aliens (male and female). Humanoid with large heads.
In an episode notable for the volume and quality of the effects, a few flaws are seen, including cut out Eagles and visible wires.
My wife, Isla Blair, did one where she had a most extraordinary makeup that was ridiculous. She and Anthony Valentine both had these appliances on. They couldn't look at themselves without laughing, which is why they did all of their scenes facing away from each other. That's the glamour of the theatre for you!
Due to the strong visual appeal of this episode, it was heavily marketed.
