Several years ago, I was flying across the mouth of the Chesapeake Bay to take some aerial photos of a site on the Eastern Shore I was appraising. Half way across, we saw two LCACs just sitting there. Now LCACs are a common sight, but two of 'em just sitting is unusual, so the pilot did a couple of circles.
First thing that seemed *really* unusual was that it appeared someone had thrown a couple of gallons of red paint through one of the propulsion fans. Then we saw tarps covering something at opposite ends of the cargo deck. Whatever took place happened just a few minutes earlier. They didn't seem too happy to have us hanging around, so we left - without taking any photos.
It wasn't until the nightly news that evening that I learned what happened. The two LCACs were practicing a towing exercise. One simulated engine failure and the other tows it. With a 2" steel cable. Which broke. Which cut some poor chap clean in two.
Now I've done a lot of winching with both Rovers I've seen several lines break, even broken a winch line myself. (A 1954 AeroParts capstan winch on the '72, and with a capstan, I've got to be right in the 'kill zone' to run it. It was ultra-low stretch dacron polyester, so it just dropped when it parted, it didn't 'store' energy the way steel can....) I treat any rope/cable under tension with utmost respect and usually drape another rope, a floor mat or tarp over the line to act as a drag on what can easily be a lethal weapon. 'Spectators' are kept well away....
