[Q]: Tower Control controls aircraft on the runway and in the controlled airspace immediately surrounding the airport. Tower controllers may use radar to locate an aircraft's position in three-dimensional space, or they may rely on pilot position reports and visual observation. They coordinate the sequencing of aircraft in the traffic pattern and direct aircraft on how to safely join and leave the circuit. Aircraft which are only passing through the airspace must also contact Tower Control in order to be sure that they remain clear of other traffic.
[A]: Who controls aircraft on the runway?


[Q]: In most nations with constitutions modelled after the Soviet Union, the legislature was given the power of being the court of last resort. In the People's Republic of China, the final power to interpret the law is vested in the Standing Committee of the National People's Congress (NPCSC). This power includes the power to interpret the basic laws of Hong Kong and Macau, the constitutional documents of the two special administrative regions which are common law and Portuguese-based legal system jurisdictions respectively. This power is a legislative power and not a judicial one in that an interpretation by the NPCSC does not affect cases which have already been decided.
[A]: What nation's model gives the power of the high court to the legistlature?


[Q]: Pomors are distinguished by the presence of Y Haplogroup N among them. Postulated to originate from southeast Asia, it is found at high rates in Uralic peoples.

Autosomally, Russians are generally similar to populations in central-eastern Europe but some northern Russians are intermediate to Finno-Ugric groups.
