https://x.com/ron_eisele/status/1769450423776141318On March 18, 1980, at 20:01:00 Moscow Time, during fueling of the Vostok-2M (8A92) launcher with a Tselina-D electronic intelligence satellite at Pad No. 4, while 141 members of military personnel were working at the pad, the launcher exploded, killing 48 people. (The actual liftoff was scheduled for 21:16 Moscow Time). A monument commemorating the tragedy was unveiled nearby on July 15, 1999 and on December 11 of the same year, the Russian government commission formally rehabilitated members of the launch team, who were initially blamed for the accident.
In the wake of the deadly accident, Pad No. 4 was shot down for three years of repairs and fire-safety upgrades. A training rocket was rolled out to the site for fitting tests on Dec. 20-23, 1982. The first post-accident launch from the site took place on April 8, 1983.
Tests were officially concluded with the resumption of launches from the site on March 21, 1984. Still, a serious accident at Pad No. 4 took place on June 25 or July 27, 1988, when a Soyuz launcher crashed between just 100 and 160 meters from the pad, damaging the facility.
