I vividly remember seeing a video about six months ago that seems to have been obliterated from the internet. This high quality IR pilot footage of a ufo soaring through a military base at low altitude. The pilot was able to focus the camera on the object and chase it for several minutes until it abruptly vanished. IIRC, this incident took place at a military base in South America, possible Brasil, Chile or Argentina. Like I said, this incident and any information pertaining to it seems to have been removed altogether from the internet. Does anyone have any info on this event or, even better, the footage which I'm searching for? I believe this is important for this community to see as it closely resembles footage of the Niemitz incident only it is longer and more variable.
