Yesterday, it was disclosed by the Pentagon that live pigs were used in testing of body armor on Humvee military vehicle simulators under fire to see how well human troops would hold up under roadside explosive blasts. About 200 tests involving explosions of pigs and sometimes rats dressed in body armor took place, to see how well human brains and bodies could survive blasts.
It has been a long known fact that pig heart and brains have some great similarity to human hearts and brains. After about 200 blasts, it was discovered that most pigs died within 24 to 48 hours of brain injury or other injury caused by the blasts while the survival rate of those pigs with body armor was much better.
U.S. car companies used to strap pigs into cars for crash tests until the 1990's when a public outcry against using intelligent animals in such live crash tests ended these research programs, and now computerized dummies are used to measure impact forces and injury damages.
