==Soyuz abort history==
Soyuz spacecraft have successfully prevented the loss of crew with a launch abort twice in its history thus far, though both cases are considered a loss of the mission.<ref name="lutomski">{{cite journal|last1=Lutomski|first1=Michael G.|last2=Farnham II|first2=Steven J.|last3=Grant|first3=Warren C.|title=Estimating the Reliability of a Soyuz Spacecraft Mission|page=3|url=https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20100014848.pdf|accessdate=7 May 2016}}</ref> Another Soyuz mission was aborted on-orbit. The successful aborts to date are
Soyuz has experienced three launch aborts and one in-orbit abort. All crew members survived the aborts.
*[[Soyuz 7K-T No.39|Soyuz 18a]], launched 5 April 1975, failed to separate the second and third stages which triggered an automated abort system. The engines on the service module were used to separate the crew from the launch vehicle.<ref name="shayler" >{{cite book | title= Disasters and Accidents in Manned Space Flight | last= Shayler | first= David | year= 2000 | page= 159 | publisher= Springer Praxis| isbn= 1-85233-225-5}}</ref> ▼

*The [[Igla docking system]] suffered an engine failure on [[Soyuz 33]] on 10 April, 1979. After consideration by ground crews, the mission was aborted by firing the back up engines and initiating a ballistic reentry.<ref name=newkirk>{{cite book | last = Newkirk | first = Dennis | title = Almanac of Soviet Manned Space Flight | year = 1990 | isbn = 0-87201-848-2 | publisher = Gulf Publishing Company | location = Houston, Texas}}</ref> ▼
