Three weeks after a pilot lost his life in a chopper crash in the difficult terrain of Arunachal Pradesh, the easternmost mountainous state of India, five more people have lost their lives in another crash of an Advanced Light Helicopter (ALH) near Migging village in Upper Siang District. The Advance Light Helicopter (Weapon Systems Integrated) aircraft was inducted into service in June 2015. This is the 12th helicopter crash reported in Arunachal Pradesh since 2009 where 90 people have lost lives.
