The expedition was the fourth mountain peak scaled under IAF’s – Mission Seven Summits, to scale the highest peaks of all continents across the world.
The team led by Wing Commander RC Tripathi was flagged in today at Air HQ, New Delhi by Air Officer in-Charge Administration, Air Marshal JN Burma. The other members of the team included Wing Commander Jaikishan, Squadron Leader N Rawat, Squadron Leader D Panda, Squadron Leader R Sagar and Junior Warrant Officer NR Choudhary.
Mt. Denali peak is considered as one of the most difficult and trickiest one to climb in terms of severity and unpredictable nature of weather. The team has already scaled Mt Everest, Mt Carstensz Pyramid, Mt Aconcagua and Mt Denali and would undertake the remaining expeditions to Mt Elbrus (Europe), Mt Kilimanjaro (South Africa) in Jul-Aug10, and Mt Vinson Massif (Antarctica) in Dec10, to accomplish the mission.
