Concerns have been raised that:

inconsistent date formats are present in the article (d mmmm format should be used throughout)
a large amount of launch information is missing
no specific references are given
an inconsistent dialect is used (British English should be used throughout)
the article uses an out-of-date header and/or footer, which requires replacement

1971 saw the last three known deaths of cosmonauts of the Soviet space program and the only deaths in space. Their mission was to man humanity's first space station. The experimental bay door failed to separate so the first crew failed to dock and second crew were killed on re-entry. 1971 also saw the launch of the first and only British satellite on top of a British rocket after that success the program was cancelled.
