For a peek into India’s aeronautical history, visit this wonderful museum past the old airport, where you can see some of the indigenous aircraft models designed by HAL. Interesting exhibits include a MIG-21, home-grown models such as the Marut and Kiran, and a vintage Canberra bomber.
You can also engage in mock dogfights at the simulator machines (₹50 to ₹100) on the top floor, though the queues for this can be considerable.
