"Destination Space" was a pilot for a series that networks declined to accept. I can understand why--this show was a bit talky and slow (which to some degree is necessary for a first show). I think more action and less talk might have resulted in the show being given the green light.
When the show begin, there's an accident aboard the space station orbiting the Earth in this sci-fi show set in the near future. A bombastic congressman takes advantage of this and the leader of the project (Harry Townes) has to go to Washington to defend his program and the high costs. Later, the action finally goes to the station and a space launch from this station is about to occur--presumably to be followed up in subsequent episodes. But there's nuclear explosion to contend with first...
When you see this today, the special effects look crappy. But for 1959, they're actually pretty good. I also appreciate that this is not a distant sci-fi show with bug-eyed monsters but a look at where folks back in '59 thought we might be in the next decades Not a great pilot but one that makes you wonder how the show might have progressed.
