There are (incomplete) K5 backups, with posts like this one[0], which happened around the time he stopped posting. Do you recall any details at all that would point anyone towards finding what you've suggested?
The backups are incomplete on Kuro5hin and several of his websites. Anything that might prove what I wrote was not backed up. He was also several nicks like Mr Markup and Repeatable Hairstyle. Because Rusty would ban him and remove his diaries because Rusty got C&D letters from lawyers about Crawford's posts. Then Crawford just came back as another nick.
This [0] is the incident report from the McDonald's. And this [1] is the referenced website post by Crawford. This [2] is the still intact place where he wrote under the pseudonym of "Jonathan Swift" (among others).
The McDonald's incident report clearly points out he believed an officer had a personal problem with him, and points to where he did a write up on it, which would not happen if it was just a cover up. It makes no mention of programming, let alone anything else. Nor do any of his writings after his release talk about planes.
Whilst his other writings are somewhat hard to follow at times, and there are places where he makes claims such Al Qaeda not existing as an entity, there is nothing about planes anywhere.
In point of fact, the only place at all, in any of the archives, or the circle of people who frequently wrote around him, the only place I can find mention of planes is this HN thread, that you have written.
I believe at this point I have been beyond generous at researching, but the simple fact is it was never related to Boeing's software.
[0] is not from McDonalds but in Portland when he lived with his mother. McDonalds was in Grover Beach California.
[1] Solving the Software problem was a human issue not a machine issue. Bugs in software are created by human beings and management tries to cover them up.
[2]Trolls took over that group and began posting sci fi porn on it.
You are mistaking but one incident in which he got arrested in Portland, OR with the Grover Beach, CA McDonalds incident. Using it as a strawman.
Mike was harassed by cops because he was mentally ill. There are several incidents of that. The McDonalds report was buried I wonder why?
Crawford would write the truth about megacorporations like Drobo and Rusty Foster would get C&D emails to remove those diaries or posts. One of his nicks was Zombie Jesus, add that one to the list.
