This was created by the Army Corp of Engineers. For all those naysayers who think they can drive into a Nuclear Plant, this may not be an airplane but these are the the concrete barriers that are in front of controlled and secure buildings at nuclear plants. The barriers will stop traffic, even trucks, from approaching the secure buildings and usually people do not believe. Here is your proof!!! Truck = 65,000 lbs. ~ Speed = 50 mph ~ Kinetic Energy = 5.5 MILLION ft. lbs. ~ Stopped in 24 inches!!!
