Pilots from across Europe have been plunging into a lake while training for an international competition.
Crews have been practising ditching their light aircraft in the water and escaping from the submerged plane in preparation for the gruelling Greenland Air Trophy (GAT2021) contest next month.
After ditching their planes in the water, they practised drills including getting into and out of life-rafts on their own and in groups, and learning how to right an inverted raft.
The pilots will face two challenges on the way, including concentrating throughout a long flight over cold water with limited fuel and unpredictable weather, followed by a precision flying-skills test using a very short or sometimes no runway.
The competition is organised by VintageAirRally, which arranges aviation events around the world.
