This "triangle" is supposed to be similar to Bermuda's Triangle. Mysterious events happen. This area is between Anchorage, Juneau, and Barrows, Alaska. An has a disappearance rate 16 times the national average. One such disappearance is in the 70's two prominent US congress men a aid an a pilot vanished in a small plane. There are plenty of questions that I could ask here an so can you. Let's discuss this an see what the best theories that come up. I'm interested more in this than the Bermuda triangle. Bermuda's triangle involves more water.
When a small plane goes down in Alaska, even a little bit off course will make it almost impossible to find with the local limited resources. Doesn't sound to mysterious to me.
