This guy has a massive pair!

No fun when an engine has a mind of its own. I had an engine in a MM1 missile hauler http://www.mace-b.com/38tmw/missiles/mm-1.htm go into self-destruct mode and tried shutting it down the normal way, but after no response I manually shut off the fuel. It continued to run for about a half-minute as it burned what was left in the lines. I can still hear the pieces impacting the thin sandwich cover between the engine bay and my legs. Fortunately, the only damage, besides the engine, was a bunch of dents in the covers. I kept a chunk of shattered aluminum block as a souvenir for years.
