Soyuz 7K-ST No.16L, sometimes known as Soyuz T-10a or Soyuz T-10-1, was an unsuccessful

Soyuz spacecraft fired six seconds before the launch vehicle exploded, saving the crew. As of 2022, it remains the only time a launch escape system has been fired before launch with a crew aboard. [1][2]

Mission highlights

The Soyuz spacecraft narrowly escapes disaster.

The crew was sitting on the pad awaiting fueling of the

payload shroud from the lower, the escape system motor fired, dragging the orbital module and descent module, encased within the upper shroud, free of the booster with an acceleration of 14 to 17g (137 to 167 m/s²) for five seconds. According to Titov, "We could feel the booster swaying from side to side. Then there was a sudden vibration and a jerking sensation as the LES activated".[4]

Just after the escape tower pulled the descent module away, the booster exploded. Its remains burned on the pad for nearly 20 hours. Four

solid-fuel landing rockets, and deployed a fast-opening emergency parachute. Touchdown occurred about four kilometres (2.5 mi) from the launch pad. The two crew members were bruised badly after the high acceleration, but were otherwise in good health and did not require any medical attention.[1] Upon being greeted by recovery crews, they immediately asked for cigarettes to steady their nerves. The cosmonauts were then given tumbler of vodka to help them relax.[4]

The

KH-11 reconnaissance satellites returned photos of the damaged Site 1 in several runs during late 1983 and early 1984. The descent module was refurbished and later used for Soyuz T-15
.

The failure's immediate result was the inability to replace the ageing

History Channel regarding the flight, Titov claimed that the crew's first action after the escape rocket fired was to deactivate the spacecraft's cockpit voice recorder because, as he put it, "We were swearing".[4]
