IMO, that sounds like a sound theory indeed. It fits with the only known fact which is that the pilot declared a training abort and that the plane actually crashed which apparently happened just after the pilot's last call.
If the pilot had a serious medical problem like lets say a stroke for example, this could IMO fit in the line of the known events that lead to the crash.
Also IMO, the other possibility could be what I posted in my first and last post here in this thread which could be a critical problem with the airframe/aircraft itself, probably related to something that went wrong in the assembly of that same aircraft. I would say the fact that only the F-35A fleet built/assembled in Japan is grounded while the fleets built/assembled in the USA and Italy aren't seem to point out that at least the investigators are seriously considering this possibility (but again these are my 2 cents).
Don't know if there could be any relation with the above or not but the F-35 that crashed was precisely the very first F-35A built/assembled in Japan...
