What it might look launching the Valley Forge into space. The movie "Silent Running", with Bruce Dern, did not show this part. It is fan fiction, and has the same Aircraft Carrier "USN Valley Forge" they used as a movie set.
Another shot of the movie set for the Silent Running system. The scale aircraft carrier Valley Forge is where the movie was actually filmed. The elevator takes you to the space Ship Valley Forge a few days before the movie was filmed.
