So while I was getting amazed with the Aircraft on display at the HAL Heritage Centre and Aerospace Museum, and the constant buzz of LCA Tejas Aircraft & MI-8 Helicopters taking off and landing at the HAL Airport across the road, I suddenly heard the load humming of rotors and instantly knew that there was a Helicopter close by.
Suddenly from behind a tree I saw this magnificent bird rise up and just float in mi air while the nose gun turret kept swivelling from side to side.
It was an HAL Rudra Helicopter with Indian Air Force markings.
