Regarding Rocketdyne Santa Susana Field Laboratory. SSFL was a research facility used mainly for the testing of rocket engines from 1949 to 2006, and nuclear reactors from 1953 to 1980. The site ended research operations in 2006. The years of rocket testing and nuclear reactor testing have left the site significantly contaminated. Environmental cleanup is ongoing. The facility is not open to the public except during occasional guided tours by the current owner, Boeing.

At the marker dedication ceremony in 2001, attendees had the opportunity to witness a rocket motor test (including me, -CB).
