916 - More nuclear test footage
Sunday, February 28, 2010



I have never seen this 2nd video before, nor have I heard much about these tests.

"Two nuclear detonations performed in a subterranean salt dome formation in Mississippi, as part of a 1960's Atomic Energy Commission Test. The test program, called Project Dribble, called for creating an underground cavity, using a nuclear bomb to do so, then later detonating a second nuclear device, as well as two gas explosives, inside the cavity. The purpose of the test was to measure the patterns of the shock waves generated by the explosions, to be better able to detect and calculate yields of similar underground tests that might be performed by the USSR.

The first detonation, to form the cavity, code-named Salmon, took place in 1964 using a 5.3 kiloton bomb, placed at the bottom of a sealed 2,710 foot shaft. The second nuclear blast, a relatively small 0.38 kilotons yield shot code-named Sterling, was exploded within Salmon's 110 foot diameter cavity more than two years later. The two conventional explosives shots were performed in 1969 and 1970."

Mississippi?!? This is all news to me, sadly my sources don't really spend much time discussing underground tests. While 5.3 and .38 KT don't sound large, they represent the explosive power in about 10 million and 750,000 lbs of TNT respectively.

Yes, those poor cows! Much larger underground blasts seem to have killed animals by ground shock effects alone.

    did the 2nd one kill the cows? Or later blasts? They mention in the first vid that no wildlife was harmed.

    These were small detonations, but it does look to me like the cows could have broken legs from this. Hard to tell though.
