On August 31st, the US Air Force celebrated the 60th year in service of the KC-135 Stratotanker. You can read a report of the official ceremony here. As part of the celebrations, the USAF produced this video to commemorate the occasion. Watch it in full-screen mode for best results.
It's sobering to think that, along with the B-52 Stratofortress it refuels, the KC-135 has been flown by three entire generations of pilots and crewmen. Today, some of its crew are the grandchildren of those who first flew the plane back in 1956 - and they're flying the same aircraft (literally the same airframe) that their grandparents did. The only aircraft to beat that performance, as far as I'm aware, is the legendary C-47 of World War II. I flew in one (operated by the South African Air Force) in the 1980's whose logbooks recorded that it had taken part in Operation Market Garden over Holland in 1944.
