A few summer space campers actually were accidently sent into space by a robot. And the oxygen in ship was running short. They had to sent someone to a space station to get the gas tanks, etc, etc.
First of all, this movie's plot is not possible in real life. But it gives a warm feelings of anything is possible if you set your heart in.
It is amazing to see those young actors who still look about the same after so many years. (I saw this movie for the first time in the year of 2000, it was filmed in 1986) There are quite a few people in that movie who are still working in Hollywood.
The view was great from outer space. It does not look unreal. It is about 2 hours long, it runs so fast that you won't even notice. You know that it is not real, but you just get sucked into it until the end.
Overall, it is a good family movie.
