OK, this really is not true.
The Spang incident is a one-off. It was tragic all around, including the bad decision to prosecute. Did anyone actually go to jail?

I've seen a lot of errors in my time on the flightline,... both from Ops and MX. And yes, if you are involved in a mishap (pilot or maintainer), you will pee in a bottle. The AF likes to check for drugs and rule it out ASAP.

I believe your statement quoted above is "sensational". Might they lose stripes? Yes. But jail time and felony charges are not levied on maintainers involved.

As for the F-15 pilots in the Blackhawk shootdown, one ended up in my squadron shortly after this to fly, but the Chief of Staff of the AF said "no way", and he never flew again in the military. Neither went to jail that I'm aware of,... but their careers were toast.
