The American government-funded secret program of identifying advanced aviation (AATIP) became public in 2017. The government has spent over $22 million on identifying these extraterrestrial beings. This program is, however, not the first of its kind. In the 1940s, the US government started a program called project sign, which was also similar to the program mentioned above.
AATIP has given the world some very interesting UFO sightings, which seem so real that you cannot call them fake.
