>From what I've read, the dropweight release on the HUNLEY was of a threaded
design, which may have failed when pressures on the weight exerted binding
forces on the release bolts, preventing the crewmembers from being able to
turn them.  A less-closely toleranced lug-in-slot arrangement (of the type I
described) might have been less prone to such failures.
