On Trending @ 10, an Air Force Day special from Hindon Air Base near the national capital. It's been a challenging year for the Air Force, a year when the Rafale controversy made headlines. The top leadership of the Indian Air Force has had to explain in clear cut terms why the acquisition of this fighter is such a priority for IAF as it faces a depleting squadron strength. Air Force Day is also about showcasing the technology of the Air Force, some of the rescue operations they have been involved in and some of the joint exercises which are increasingly a key part of what the Indian Air Force strives to do in this region.
