The UFO's on Gerry Anderson's UFO
had a distinctly Apollo reentry module shape,
but also in addition had a characteristic spinning belt of beam emitters that could wail on the unsuspecting. This
is not the best image of one, but it is good for recognition.
I thought you might like to be reminded of/made aware of Anderson's iconic craft with an otherwise similar profile, so that you can avoid any unintentional resemblance in the atmospheric flight characteristics of your landing module.
For, if your craft moves through the air horizontally while traveling around within a planet's atmosphere, it could easily strongly resemble an Anderson UFO. This could be remedied by making movement from point A to point B on a planet generally ballistic, so that motion is generally along its main cylindrical axis.
