Prof Opmmur...Im sure you remember in Aug12th 1963 the people at Montauk had to create an electronic damping system for the returning time-wave from the PX, which would have caused havoc on the Earth...For any member not knowing about this you can Google Atlanticus not Revisted, which happened to be the project name for that at Montauk.

...
.It was discovered that there are 10 and 20 year "node" points concerning the PX, the 1963 node point was exactly on Aug12th and the 20year node point occurred exactly on Aug12th 1983, where the Montauk scientists created a link with the Destroyer DE-173 as it was in hyperspace.

..please remember that the date for the first successful PX was Aug12th 1943
