The top section of this green-painted Boeing 737's fuselage was slightly faded and I noticed a few dark-green, rectangular patches on its top. They look like patch kits on a bicycle tyre's inner tube. What are they? My understanding is that hairline cracks/weaker spots in the fuselage can't simply be patched like this?

It still has un-patched security vulnerabilities. And Microsoft is never going to fix it. Instead they are telling us that you should use/buy their new OS... which is also full of bugs and new undiscovered vulnerabilities... because their old OS is not safe to use (anymore). It was never safe!
