April 1982. Argentina invades the Falkland Islands. In response, Britain despatches a naval task force. Eight thousand miles from home, its fate hinges on just twenty Sea Harriers against the two hundred-strong might of the Argentine Air Force. The odds against them are overwhelming. The MoD's own estimates suggest that half the Harriers will be lost in the opening days of the conflict. They need backup. Within three weeks 809 Naval Air Squadron is reformed, trained and heading south, ready for war. Not since World War Two was so much been expected of such a small band of pilots.
