July, an incident which lasted 40 days, making it one of the longest. This record was later beaten in 1999. As a result of the evolving threat, President Nixon issued a directive in 1970 to promote security at airports, electronic surveillance and multilateral agreements for tackling the problem. The International Civil Aviation Organization (ICAO) issued a report on aircraft hijacking in July 1970. Beginning in 1969 until the end of June 1970, there were 118 incidents of unlawful seizure of aircraft and 14 incidents of sabotage and armed attacks against civil aviation. This involved airlines of 47 countries and more than 7,000 passengers. In this period, 96 people were killed and 57 were injured as a result of hijacking, sabotage and armed attacks. The ICAO stated that this is not isolated to one nation or one region, but a worldwide issue to the safe growth of international civil aviation. Incidents also became notoriousin 1971, a man known as D. B. Cooper hijacked a plane and extorted US$200,000 in ransom before parachuting over Oregon. He was never identified. On August 20, 1971, a Pakistan Air Force T-33 military plane was hijacked prior the Indo-Pakistani war of 1971 in Karachi. Lieutenant Matiur Rahman attacked Officer Rashid Minhas and attempted to land in India. Minhas deliberately crashed the plane into the ground near Thatta to prevent the diversion. Countries around the world continued their efforts to tackle crimes committed on-board planes. The Tokyo Convention, drafted in 1958, established an agreement between signatories that the "state in which the aircraft is registered is competent to exercise jurisdiction over crimes committed on board that aircraft while it is in flight". While the Convention does not make hijacking an international crime, it does contain provisions which obligate the country in which a hijacked aircraft lands to restore the aircraft to its responsible owner, and allow the passengers and crew to continue their journey. The Convention came into force in December 1969. A year later, in December 1970, the Hague Convention was drafted which punishes hijackers, enabling each state to prosecute a hijacker if that state does not extradite them, and to deprive them from asylum from prosecution. On December 5, 1972, the FAA issued emergency rules requiring all passengers and their carry-on baggage to be screened. Airports slowly implemented walk-through metal detectors, hand-searches and X-ray machines, to prohibit weapons and explosive devices. These rules came into
