UFO – Have you ever heard of the Area 51 in the Nevada desert?
Pereira – Yes. The area is a real thing and we conducted some exercises there. Not in the Area 51 itself, but over the Nevada desert where many military facilities are located. The USAF performs exercises all over that place. It has international cooperation and invites military from many countries for training sessions there. We took part in a training program there and heard of the Area 51, but no one is allowed to enter there. The Brazilian Air Force (FAB) has already sent two teams to exercise there and I was leading one of these operations. One interesting thing is that all exercises avoid Area 51 which is located right at the center of everything.

UFO – Aren't there any incidents of pilots trespassing those borders?
Pereira – Yes. The biggest problem is to make foreign pilots understand the procedures to be followed. Not even US nationals are allowed to fly over that space.
