A restored M4A1 Sherman Tank was used to knock down part of a building being demolished for the new "Tank Arena" at Paul Allen's Flying Heritage Collection (FHC) at Paine Field in Everett. This happened on past January 15, 2014. The "Tank Arena" is a space about 26,000 square foot, where the collection's tracked vehicles and tanks can be operated during demonstrations. The "Tank Arena" was completed in time for "TankFest Northwest" Memorial Day, celebrated past May 26, 2014.
