This sound a little weird but about a year ago a friend of my wife came to our house, along she brought a friend also, It happens that this person (a man) and I started to talked about different things and we brought the subject of ufo's and area 51, he told me that he is in the air force and and that he visited the so called area 51 where he along with others buddies were subject to a rigorous security debriefing (I have to said that before we started talking about ufo's he told me that he was in the air force.)

As our conversation keep on he told me that he saw photos taken probably in the early 20th. century were it appear a stealth fighter aircraft, if this was true I suppose that in area 51 they were experimenting with time traveling or maybe this person was pulling my leg. Does anyone had hear anything about this, I appreciate any help. Thanks.
