The Princess Royal has been welcomed aboard a plane belonging to the Mission Aviation Fellowship (MAF) - the world's largest humanitarian airline, made up of Christians delivering help to those in need.
During her royal visit to Uganda last week, HRH Princess Anne and her husband Sir Timothy Laurence travelled from Kajjansi to Mbarara, and then to Masika, via the small plane.
The Vice Admiral - who married into the Royal Family in 1992 - called the organisation "very impressive" after hearing about their work.
The Christian organisation flies medical equipment and relief to people in hard-to-reach places. Recently they responded to an earthquake in Papua New Guinea which left nine people dead and many buried under landslides.
The Princess Royal is no stranger to the MAF fleet, having flown with them a number of times including, most recently, on a trip to Bangladesh in 2016.
Ruth Jack said: "It was a real treat to fly the Princess Royal and her husband, both were very engaged and interested in our work. I'm so pleased that the Princess has been able to experience MAF in action and see first-hand the lifesaving work our aircraft enable across Uganda."
Kate Airey, British High Commissioner to Uganda who accompanied the Royal tour said: "It has been such a help to have the support [of MAF Uganda] on this important visit. They are a lovely organisation doing great work in Uganda."
