Upon seeing the outdoors for the first time in 30 years, a group of chimpanzees in Austria broke out into wide grins and leapt into the grass. The chimps, who had been used for medical research by a pharmaceutical company, had been kept in cages for most of their lives.
Testing on the chimps ended in 1997, when the pharmaceutical company was bought by American organization Baxter, but it took until now to get the animals back outdoors. The apes' keepers had to help them get readjusted to the idea of a world beyond their enclosure, and it seems all the hard work has paid off.
When the door to the facility opened, the chimps hugged each other and stared in amazement at their new world. They will now continue to enjoy a freer universe at an animal sanctuary outside Salzburg.
