In the 70's I watched a movie that stuck in my mind, but I don't remember the name. Can anyone help me?
The plot is as follows:
The movie is in the current day (1970's). In the US (Houston), NASA is planning on sending the first manned vessel into space. The story follows the astronaut and his family preparing for the voyage. The spacecraft is launched successfully, but after a few days in space has difficulties and loses radio contact with the base. Back at the base they assume it is lost and that the astronaut is dead. They have another craft which they bring up to readiness to launch.
At the time of the launch, once the launch sequence has started, the first craft suddenly appears heading back to earth with the astronaut alive; however, he does not have control of the craft and it is running on automatic. The first craft crashes into the second craft, causing major destruction of the launch site. The move ends with the program director (who is in a wheelchair) looking at the debris a few weeks later.
