Visual-effects scenes of Alan Shepard's flight show the Redstone rocket emitting a long bright engine flame and leaving a thick white smoke trail. This is characteristic of a solid rocket. The Redstone's main engine burned ethyl alcohol, so it produced a small pale flame that was barely visible from a distance. The visual effects are mixed in with stock footage of actual Redstone launches, making the discrepancy even more noticeable.
