 Facts
  1. The Nedelin disaster: It took almost three decades before the Russian public found out what really happened in October of 1960. Marshall Mitrofan Nedelin (who many blame for the disaster) was reportedly sitting 15 to 20 meters away from the rocket at the time of the massive explosion.
  2. Since April 12, 1981 two NASA Space Shuttles have been destroyed in 114 missions, both with the loss of the entire crew. This adds up to a 2% death rate per astronaut per flight.
  3. The Vostok rocket is the same type of two-stage booster that was used to send the Soviet astronaut Yuri Gagarin into orbit in 1961.
  4. According to official Chinese sources the Chinese Long March 3B rocket carrying an Intelsat 708 satellite crashed 1850 meters away from the launch pad into a nearby mountain village destroying 80 houses and killing 6. Unofficial accounts list the death toll at more than 500.
  5. According to Brazilian sources, one of the VLC-3's four motors caught fire, triggering an explosion which caused the launchpad to collapse as technicians were carrying out final tests.
