Their first home deployment came on 7 January 1975, when an Iranian armed with a replica pistol hijacked a British Airways BAC One-Eleven that landed at Stansted Airport. The hijacker was captured alive with no shots fired, the only casualty being a SAS soldier who was bitten by a police dog as he left the airliner. The SAS was also deployed during the Balcombe Street Siege, where the Metropolitan Police had trapped a PIRA unit. Hearing on the BBC that the SAS were being deployed the PIRA men surrendered.
