Soaring over the Niger river before entering the savannah in northern Mali, a Canadian twin-engined military helicopter is making one of its first forays into the country.
Two artillerymen are scanning the ground below when the pilot announces that "one of the gauges has stopped. We only have one engine left".

As Canada sends its first peacekeepers force to Africa in 24 years, they are discovering a conflict -- and weather conditions -- unlike anything they have dealt with in a long time.
They have joined one of the United Nation's most difficult and dangerous missions -- the 14,000 strong MINUSMA operation in Mali, a linchpin West African country in the vast, arid Sahel region.
Flying in northern Mali, which is mostly covered by the Sahara desert, "is like working in the Arctic, you just swap ice for sand and -40 degrees for +40," jokes lieutenant-colonel Chris Morrison, commander of the Canadian air troops in the northeast city of Gao.
Aircraft have to operate in extreme conditions in the Sahara and "there are few runways to land on" for repairs or refills, says Morrison, whose previous missions include Bosnia and Afghanistan.
- Canadians back in blue helmets -
While it was Canada that helped mastermind the idea of large-scale UN peacekeeping missions back in the 1950s, it hasn't deployed significant numbers of "Blue Helmet" troops -- as the peacekeepers are known -- for more than a decade.
Nevertheless, Prime Minister Justin Trudeau is keen for Canada to return to peacekeeping operations, not least in a bid to secure a non-permanent seat on the UN Security Council in 2021.
And the Mali mission marks the return of the Canadian military to Africa for the first time since the Rwandan genocide in 1994, when Ottawa lead the UN mission there.
Since last month, a contingent of 250 Canadian soldiers and six helicopters -- two Chinook flying ambulances and four Griffon attack aircraft -- have taken over from German troops in conducting medical evacuations.
They are stationed at Camp Castor in Gao with around 900 German and 100 Dutch soldiers.
Not far away, another 4,000 soldiers from non-NATO countries are stationed in the UN "Supercamp".
UN's most dangerous mission
MINUSMA is currently the UN's most dangerous peacekeeping mission.
Since it was deployed in 2013, over 170 members have been killed -- more than half the UN soldiers killed during this period around the world.
Islamist extremists linked to Al-Qaeda took control of the desert in northern Mali in early 2012, but were largely driven out in a French-led military operation launched in January 2013.
However, large stretches of the country remain outside the control of the Malian, French and UN forces, which are frequent targets of attacks.
"We want to help the UN, but it is a difficult mission," says Chris McKenna, commander of the Canadian troops in Mali.
"It is complicated, but it is what we expected. The environment is harsh, with dust and heat. Working in a multi-lateral, multi-national environment comes with challenges, but we are doing very well," McKenna insists.
The soldiers themselves are happy about Canada's return to the Blue Helmets.
"It is a good thing to be back," says major Dominique Simard, a helicopter pilot. "We are here to saves lives, it is rewarding."
The Canadian troops only take part in flying missions and are not deployed on foot.
And when they are not out in their helicopters, the soldiers are not allowed to set foot outside Camp Castor.
To pass the time, they have internet access, postal services, a cafeteria staffed with Indian cooks, a gym and a bar that does not serve alcohol.
But it's not easy being cooped up for so long.
"600 meters (2,000 feet) by 600 meters for seven months," one officer complains.
"Every day, we are in the sky, 35 feet above the theatre of operations, but we are not going to have terrestrial convoys, we are not equipped for it. That is not our mandate," says McKenna.
