I had the amazing chance to enter a Boeing B-52 Stratofortress and see it from inside. This very plane was built in 1961 and is still on active duty, at least till 2020. It seems like nothing was modernized since then as you can see on the photos below. Climbing through the cramped inside and sitting in the cockpit was quite a surreal experience. Big thanks to the crew!
