The most expensive aircraft in the world, the B-2 Spirit stealth bomber has been spotted flying in the skies over Ipswich and the Scenic Rim. Three US Air Force Northrop B-2 Spirits, also known as the stealth bomber, have arrived at Royal Australian Air Force Base Amberley in recent days. The strategic bomber has enhanced stealth capabilities, with a distinct design to avoid radar detection and a wingspan of 52m, while it has the capacity to deliver both conventional and nuclear weapons. #aircra
