This is part of the special effects storyboard for episode 23, The Immunity Syndrome.

Scene 98A, Slate 28X. REPLACEMENT. Eagle enters bottom frame heading for distant planet.
The script direction is "Eagle Three and glider heading towards the distant planet." It is not known why this is marked "Replacement".
Scene 104, Slate 30X. Eagle and re-entry glider - track in close on glider.
The original script direction was "CLOSE ON EAGLE THREE. CAMERA jibs up to the glider aloft." The storyboard portrays a wide shot of the Eagle, tracking into the glider, but it is written over with a large asterisk and the words in chinagraph "jib up". In filming, they follow the script direction rather than the storyboard, with a close-up vertical pan from passenger module to glider. The large Eagle section and spine are used, not the 44 inch Eagle. Perhaps the storyboard shot was intended to avoid creating a special model setup.
Scene 110, Slate 31X. Eagle & glider travelling in unison. Sky now dark blue, stars can be faintly seen.
Scene 112B, Slate 34X. The Eagle hurtles upwards like an express elevator.
Scene seems to have been filmed but was cut.
Scene 117, Slate 36X. Huge storm clouds directly ahead.
In the episode we see this view twice, inbetween other model and studio shots. There are also studio shots with the astronauts in front of the window, which in one shot shatters over them.
Scene 121, Slate 37X. Glider thown about by the massive turbulence.
In the episode this is cut into two shots.
Scene 125, Slate 38X. A massive streak of lightening hits the craft.
In the episode there are two shots each with lightning strikes, the second which causes an explosion on the rear of the glider. There is also an additional distant shot.
In Johnny Byrne's script there is no lightning strike; in scene 123, the last third of the glider's wing is torn off; in scene 125, the plastic covering of the other wing rips away, exposing the struts.
Scene 127, Slate 39X. Glider rushes towards planet thru' clear blue sky.
The editor moved this scene back - it is the first shot we see of the glider on its own (before it enters the clouds). This introduces a continuity error, as the landing skids are visible, but they were still stowed in the next shot.
