This project began as a simple message illustration. At the 2011 Global Leadership Summit, Rev. Dr. Brenda Salter McNeil asked for a loud explosion in the auditorium during her talk as she discussed Chuck Yeager’s sound barrier breaking flight. When the Willow Creek discussed this with Prolifik, we decided we could do better than that. After a trip to the Smithsonian and numerous runs to the Army supply store, we built this piece.
