    【Question】
    For the flight with the tail number 'N702SK', which air carrier does it belong to? tail number refers to TAIL_NUM; TAIL_NUM = 'N702SK';

    【Evidence】
    tail number refers to TAIL_NUM; TAIL_NUM = 'N702SK';

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT T2.Description FROM Airlines AS T1 INNER JOIN `Air Carriers` AS T2 ON T1.OP_CARRIER_AIRLINE_ID = T2.Code WHERE T1.TAIL_NUM = 'N702SK' GROUP BY T2.Description
