Why Did These 10 Men Die? (Willamette Week, 1997)
Some insightful journalism about the C-130, coincidentally from a Portland newspaper. There's lots in there about maintenance, politics, and the in's and out's of military crash investigations. There are a bunch of sidebars and followups on the main page, most of which are mostly worth reading.
For those of you who may remember, this was the "King 56" case. Ten Air Force Reservists died when their C-130 crashed just off of the Pacific coast. The problem appears to have been "four-engine rollback", a malfunction in the box that keeps the engines out of phase -- it kept slowing all 4 of them.
These articles may not apply directly to the problem at hand; but, it's very good reporting, and it may resonate with the current discussion. I remember this being a very big deal when it came out, esp. since this "alternative weekly" was the only media outlet that dedicated resources to uncovering the truth.
