CREATE TABLE operate_company (type VARCHAR, id VARCHAR)
CREATE TABLE flight (Id VARCHAR)

What are the distinct types of the companies that have operated any flights with velocity less than 200?
SELECT DISTINCT T1.type FROM operate_company AS T1 JOIN flight AS t2 ON T1.id = T2.company_id WHERE T2.velocity < 200
SELECT DISTINCT "T1"."type" FROM "operate_company" AS "T1" JOIN "flight" AS "t2" ON "T1"."id" = "T2"."company_id" WHERE "T2"."velocity" < 200
