So as a pilot you can't override the software to stop it from "thinking that the plane is on the ground" mode? Something similar happened recently with A320 when it didn't want to land on an airfield during emergency unless it was flown in a special mode. But F-35 doesn't have that?

Who eats the loss under such circumstances? Government or Lockheed Martin or are these 200 million dollar jets insured ?
Earlier quoted context omitted.
Likely contamination of ground handling equipment [1]. Unfortunately can happen. I wonder if the hydraulic fluid is hygroscopic or something? 1. https://www.pacaf.af.mil/Portals/6/documents/3_AIB%20Report....
Hydraulic brake fluid is glycol ether based and hygroscopic. Planes usually use mineral based fluids which are not, but heck if I know what the F-35 uses.
The F-35 Joint Strike Fighter uses a specialized hydraulic fluid that’s based on a synthetic ester formulation, not a petroleum-based fluid.
Specifically, it uses phosphate ester–based fire-resistant hydraulic fluid (commonly in the MIL-PRF-83282 or newer MIL-PRF-87257 class).
Apparently the older phosphate-ester based hydraulic fluids were hygroscopic but I'm not sure if the newer variants are.
We have no alternative we can get before 2035. They are talking about extending the F/A-18 but since we would be the only ones still using them we would have to pay for that too at who know what price.
The public approved 6 billion and now it looks like it will be way more, excluding skyrocketing maintenance which is not included and a patriot missile system that when it is finally delivered will cost who knows how many billions.
The whole thing is an absolute shit show here and that's ignoring the technical issues this thing has...
But why was there water in the hydraulic system in the first place?
