Ah, yes, this would be the same kind of movie that has a rocket ship that somehow manages to get to other planets - evidently moving fairly close to the speed of light, or it'd take them months to years to get ANYWHERE - powered by a truely pitiful stream of smoke? And also takes off in, coincidently enough, an exact reverse of the way they landed? (And just how the HELL were they supposed to land - or turn - with only the ONE engine?)

Movies like that are part of the reason I'm a big MST3K fan. ^_^
