Heartwarming moment lab chimp named Vanilla kept in a cage her whole life sees the sky for the first time

THIS is the touching moment a chimpanzee which lived its life in a lab finally saw the open sky for the very first time.

For the first 29 years of chimp Vanilla's life, she only saw the inside of a brutal testing laboratory - but her new digs in an animal sanctuary allow her freedom like never before.

The heartwarming video shows Vanilla entering the enclosure and being hugged by the "alpha male" Dwight.
