I don't believe the story. It's elaborate in scope and would have made a good early draft for an Indiana Jones movie. Much like the Philadelphia
Experiment, it's almost wholly based on the account of one man. Subsequently, guys have appeared to support and add to the story. Unsurprisingly,
they bring nothing that can be substantiated.
These stories usually have a small clique of people from the book circuit that use each other for reference and support. "Bob said.." and "John
said..." takes on this reality that is superficial and falls apart when independent evidence is requested. Wikipedia isn't the holy grail of
accurate information, but it's useful in this case. Look at the 'further reading' and 'external sources'
on the Montauk Project page. Not a lot of names there is there? Same names repeated.
Conmen, hucksters, hoaxers and the self-deluded. Dulce Alien Bases? Again just one man with a good way of talking and no evidence. Same patterns, same
elaborate tales that grow and develop into the fabric of some illusional reality.
