I want to know the answer to the following question:
When established in 1928, which airport served as the base of the Delhi Flying Club?
All the background I'm provided with is that "The Delhi Flying Club, established in 1928 with two de Havilland Moth aircraft named Delhi and Roshanara, was based at Safdarjung Airport which started operations in 1929, when it was the Delhi's only airport and the second in India.". Is that enough to answer the question?
Answer: yes
