Pilot Gabe Zeifman shared footage of the Nevada Training and Test Range (NTTR), better known as Area 51, after a Dec. 25 flight.
Zeifman, an air traffic controller in training, flew his small Cessna 150 plane around Lake Papoose, near the military base.
As reported by Mystery Wire, the pilot flew over the area on three separate occasions.
In videos of his flights, posted on YouTube, Zeifman can be heard getting clearance for his route in the restricted area.
For this particular flight, Zeifman had high-quality camera equipment that allowed him to take better pictures.
In the photos you can see Area 51, and some netizens have noticed a strange triangular structure inside a hangar.
The mysterious object is blurry and it is not possible to determine exactly what it is, but everything seems to indicate that it could be an aircraft, probably a reverse-engineered extraterrestrial technology, more specifically a triangular UFO.
