Reblogging because it’s cool engineering stuff. Testing it vital to being sure. There was a day that Sandia Lab needed to know exactly what would happen if a plane hit the wall of a containment vessel They tested because that was the day when they needed to know what would happen when an aircraft hits a wall at 500 MPH.
Do I need to say anything else?
1977 collision test of F4 at full speed and a mock up wall of a reactor containment. The wall won.
