Two F-22 Raptor fighter jets of the 95th Fighter Squadron from Tyndall, Florida, and an A-10 Thunderbolt (R) from Whiteman air force base, Missouri, approach the refuelling nozzle of a KC-135 Stratotanker from the 100th Air Refueling Wing at the Royal Air Fore Base in Mildenhall in Britain as they fly near the Estonian capital of Tallinn towards the newly established NATO airbase of Aemari, Estonia September 4, 2015. Four F-22 Raptors and some 60 airmen were deployed to Spangdahlem Air Base, western Germany, to train with allied air forces such as Poland and Estonia. The first-ever training deployment of the 5th fighter generation to Europe is part of the European Reassurance Initiative. REUTERS/Wolfgang Rattay
