The form "BC" is specific to English, and equivalent abbreviations are used in other languages: the Latin form, rarely used in English, is ante Christum natum (ACN) or ante Christum (AC).

The EEC was also known as the European Common Market (ECM) in the English-speaking countries, and sometimes referred to as the European Community even before it was officially renamed as such in 1993. In 2009, the EC formally ceased to exist and its institutions were directly absorbed by the EU. This made the Union the formal successor institution of the Community.

Air India Flight 855 was a scheduled passenger flight from Bombay, India, to Dubai, United Arab Emirates. On 1 January 1978, the Boeing 747 operating the flight crashed into the Arabian Sea about 3 km off the coast of Bandra, only 101 seconds after take-off, killing all 213 passengers and crew on board. An investigation into the crash determined the most likely probable cause was the captain becoming spatially disoriented and losing control of the aircraft after the failure of the captain's ADI, one of the most critical flight instruments and lack of crew co-ordination. It was Air India's deadliest air disaster until the bombing of Flight 182 in 1985 and was the deadliest airliner accident in Indian history until Charkhi Dadri mid-air collision in 1996. It is currently at third for both categories after being surpassed by Air India Flight 171 in June 2025.
