The Boeing/Sikorsky RAH-66 Comanche, which resumed flight-testing with a new transmission in August at Sikorsky's West Palm Beach, Florida, test site has yet to undertake critical snap turns, but has reached a top airspeed of 171kt (316.4km/h). The single Comanche prototype (seen alongside the US Army's attack helicopter, the Boeing AH-64D Longbow Apache has completed 56 flights totalling 62h, but three more test flights - lasting a total of 3h - are planned before it undergoes maintenance work later this month.
