According to the National UFO Reporting Center, there has been over 430 reports filed with NUFORC since 1994 regarding "black triangles" and other similar objects.  Because of the obvious problems of identification this class of reports has been somewhat neglected. This Training Information Series is a step forward in the handling of such cases. Any state op who has a report that needs to be checked for MADAR data needs to file a request.

As far as I know David Marler is our chief expert on BTs and we are hoping to get some input and a briefing video posted in the days ahead. In the meantime here is his book on Amazon:

They have become legendary in UFO circles. Huge, silent-running "Flying Triangles" have been seen by ground observers creeping through the sky low and slow near cities and quietly cruising over highways.
The National Institute for Discovery Science (NIDS), has catalogued the Triangle sightings, sifting through and combining databases to take a hard look at the mystery craft. Based in Las Vegas, Nevada, NIDS is a privately funded science institute with a strong research focusing on aerial phenomena.The results of their study have just been released and lead to some unnerving, still puzzling conclusions. The study points out: "The United States is currently experiencing a wave of Flying Triangle sightings that may have intensified in the 1990s, especially towards the latter part of the 1990s. The wave continues. The Flying Triangles are being openly deployed over and near population centers, including in the vicinity of major Interstate Highways."

A key NIDS conclusion is that the actions of these triangular craft do not conform to previous patterns of covert deployment of unacknowledged aircraft. Furthermore, "neither the agenda nor the origin of the Flying Triangles are currently known."

The years 1990-2004 have seen an intense wave of Flying Triangle aircraft, the study observes. Sifting through reports by hundreds of eyewitnesses, the NIDS assessment states that the behavior of the vehicles "does not appear consistent with the covert deployment of an advanced DoD [U.S. Department of the Defense] aircraft."
Rather, it is consistent with (a) the routine and open deployment of an unacknowledged advanced DoD aircraft or (b) the routine and open deployment of an aircraft owned and operated by non-DoD personnel, suggests the NIDS study.
"The implications of the latter possibility are disturbing, especially during the post 9/11 era when the United States airspace is extremely heavily guarded and monitored," the NIDS study explains. "In support of option (a), there is much greater need for surveillance in the United States in the post 9/11 era and it is certainly conceivable that deployment of low altitude surveillance platforms is routine and open."

According to Colm Kelleher, NIDS Administrator, the newly completed quasi "meta-analysis" of Flying Triangles melds three major U.S. databases: NIDS, the Mutual UFO Network (MUFON) and data collected by independent researcher, Larry Hatch, the creator and owner of one of the largest and most comprehensive UFO databases in the world.
Kelleher said, the analysis indicates that deployment of Flying Triangles is open, not covert, and involves low-flying, brightly lit aircraft routinely deployed over populated areas including cities and Interstate highways.
"However, I cannot say whether these are U.S. Air Force aircraft. We simply don't know," Kelleher told "But it does not appear to be consistent with the covert patterns of deployment we saw with the F-117 and B-2 prior to their acknowledgement. This is open, even brazen," he stated.
