"outside collecting rust" seems a little harsh. Aren't planes designed to be outside 24/7 under conditions a bit more strenuous than being parked?

- dvdkdndjc 7y agoWell not necessarily more strenuous. Parked they’re exposed to the ground level weather, which might be harsher than in the air. - Less water - Less sodium if parked near a sea Chemically it seems better to be above the clouds then bellow them.
- Aloha 7y agoI believe the bulk of the produces MAX's are parked in renton near the factory - or at Boeing Field in Seattle.
- burfog 7y agoChemically, a big factor is ozone at high altitude. It has caused window problems.
- cesarb 7y agoI read somewhere that the most strenuous thing to an aircraft's structure is pressurization cycles, which properly parked aircraft aren't going through.
- dredmorbius 7y agoTechnically: aluminium doesn't rust, it corrodes. The corrosion in air is near instantaneous, and, unlike rust on iron, forms an impervious barrier, preventing further degredation. Mind: aircraft are not comprised entirely of aluminium, and there are components which may suffer degredation. Airframe-as-a-whole, however, not so much. There are also aircraft which have been in continuous active service for decades -- the DC-3 and B-52 being two notable cases. These do see periodic overhauls, but net environmental exposure isn't the limiting factor. Flight-cycles, and cumulative metal fatigue (a distinct problem of aluminium to a much greater extent than iron or steel) is. Both wing flex cycles and pressurisation/depressurisation (takeoff-landing cycles) are far more significant.
