Of all of the pills that Paul Dehn (screenwriter) asked us to swallow, that was by far the hardest.
And yeah even though it doesn't make a lick of sense, the image of the three apes taking off the helmets had a huge impact on me when I was 8 in a darken movie theater.... and it is something that has always stayed with me. The scene is perfectly punched up by Jerry Goldsmith, who wrote the film score of the first film.
Speaking of Escape, it is funny that the film asserts that it's Taylor's ship that the chimps used to travel... however it's way too small to be Taylor's ship and the whole hatch opening (the hatch that was blown in the first film for the astronauts to escape) and sensor pole are missing from the spaceship altogether.
Oooops!
