Myanmar climbers eye Hkakabo Razi -the peak conquered only once

These climbers from Myanmar are training for the challenge of their lives. They're preparing to take on the treacherous mountain, Kakapo Razi, in their country's far north. The peak, thought to be nearly 5,900 metres high, has only once been conquered, and that was more than 20 years ago. There's a risk we won't come back alive, but we're doing what we can to prepare, both physically and mentally. The climbers have even been to Nepal for training. Team member Piepio Aung is one of only two people from Myanmar known to have summited Mount Everest. But he says that's easy compared with the route they'll be taking up Kakapo Razi that starts with a two-week-long jungle trek and ends on a jagged ridge of icy pinnacles. And unlike Everest, it's also completely isolated. Even if you're 70 years old, you can get to the top of Everest if you can pay people to pull you up. Getting used to low oxygen levels is crucial in training. If they make it to the top, they'll also confirm using GPS if Kakapo Razi is Southeast Asia's highest peak or not. A long-running dispute. A Japanese-Myanmar duo conquered it in 1996 without GPS. This time, the team is proudly all Myanmar. We want to show that Myanmar people can do this. We plan to plant the nation's flag at the summit. A previous Myanmar-only attempt in 2014 ended in tragedy. The climbers never returned and a rescue helicopter crashed, killing one pilot. This time, they'll have several rescue helicopters on hand for the two-month journey off the beaten track. A chance to leave a trail of inspiration for others in a country that only has a few dozen climbers.
