San Carlos Airport (IATA Airport Code: SQL) is a small general aviation airport located in San Carlos, California. Adjacent to the airport is the Hiller Air Museum.
The main runway is 2,600 feet (792 meters) long. Aircraft with maximum gross weight in excess of 12,500 pounds (5,670 kiligrams) are prohibited from operating from San Carlos Airport.
Given its proximity to the headquarters of the Oracle Corporation, a maker of database software, some have speculated that the airport code of SQL is a humorous reference to this large neighbor; in databases, SQL stands for Structured Query Language. This appears not to be the case, as the airport was named well before the founding of the Oracle corporation.
