CHINOOK SUNSET: A U.S. Army Chinook on a mission at sunset. Here’s some background on the CH-47F and CH-47D models. It includes this observation: “CH-47s will still be at work in the 2060s. The CH-47 will end up serving about 100 years.” Additional photo: A CH-47 in action with the 82nd Airborne in Afghanistan.

UPDATE: I’m told the StrategyPage certificate issue was fixed as of 12:15 pm CDT. It was not a hack. Thanks to the commenters who noted the problem.
