ITBP has floated a tender to hire high-altitude recovery agency to retrieve the body of climber Lance Naik Dorje Morup, known as "Green Boots", from Mount Everest, The Tribune reported. Morup's body has remained in the mountain's Death Zone above 8,000 metres where oxygen levels are extremely low, for nearly 30 years. He had died during the 1996 Everest expedition.
