 Both the Xindi landing pod and the alien spaceship were designed by John Eaves . He also produced a series of designs for a Vulcan shuttle which ended up being written out of the episode . The Xindi pod went through three designs being approved , while the alien spaceship was accepted on the first submission . However Eaves regretted this , as he had submitted a spaceship design which he strongly disliked , calling it " by far my least favorite of anything I have ever drawn " . It was based on a hatchet housed in a tool pouch . Eaves also developed the concept artwork for the alien temple .
