Stress relief. Look up the history of the British Comet airliner...
The Chinook can "land" (alight?) and operate briefly on water so I guess technically that counts as "nautical". I just realized something. One of my mentors early in my Engineering career was a son of a Pan Am Clipper seaplane Capitan and he always called landing "alighting". I guess you can't "land" on the sea.
The Comet was pressurized, CH-47 is not. Some have blister type windows for observers. The CH-47 has kept up with the times.
Mostly we used them to check the engines and aft rotor condition.
Shithooks. They leak hydraulic fluid all over and if they don't leak you don't fly cause they are empty.
It fun to be a passenger when the sling loaded Humvees start oscillating.
"The One That Went Inverted" should scare hell out of anyone with an active imagination.https://chinook-helicopter.com/history/aircraft/D_Models/84-24156/84-24156.htmlToward the end, click on the link "A Flight Fax article concerning the roll incident" for the crew's impression of events.
My mother made wiring harnesses in the factory in PA. Dad worked in the paint dept. Late 50's/early 60's. Union shop. He didn't last long. Union idiocy made no sense to him. He was the best painter they had, but he wasn't rated to do finish paint. (he was actually an autobody man) If the paint had a run, the whole ship had to be stripped and repainted. Several times the painter would screw it up, and leave for the day, since it took time to strip it. He would fix it and finish the paint job so the schedule could be met. One day the painter didn't even show up, and it had to be ready for acceptance the next day, or they would be in trouble due to the government contract. He painted the whole ship, saved the contract, and they fired him for doing it.
