The Great Lakes Triangle by Jay Gourley

Paperback. Condition: Good. 1977. Fawcett.

What is the mysterious force at work over the Great Lakes of America and Canada that - with devastating speed and power - destroys hundreds of aircraft and ships that venture there?What causes aircraft with perfectly working engines to suddenly lose power?Why do gyroscopic and radio instruments fail for no apparent reason, and with tragic results?Strange flying objects capable of incredibly powerful acceleration have been observed there. Could they be responsible?What causes highly qualified pilots to simply lose control of their aircraft, and why do their normally competent crews behave irrationally? Most strangely, why do survivors of these Great Lakes disasters seem to remember nothing of the events?These are some of the intriguing questions that Jay Gourley asks in this chilling roll-call of extraordinary catastrophes - events that both U.S. and Canadian authorities have classified as having "undetermined" causes.
