Demolition/Sabotage/Booby-Trap explosive charges

Something almost never heard of is the Demolition/Sabotage/Booby-Trap explosive charge, usually deployed in the event of a crash or forced landing in enemy territory to prevent the aircraft or various pieces of its intelligence-sensitive equipment from being captured.

So, the purpose of this post is to provoke discussion of the topic, be it technical descriptions of the munition types, deployment procedures or standing orders, anecdotal stories - amusing or serious, historical or recent, etc, etc.

I myself, remember reading an account of the allied capture of German WWII aircraft and the technical recovery/investigation teams subsequently finding explosive demolition charges concealed in the wings.

To give you something to ponder have a look at the equipment schedule for the Spitfire which includes one of said explosive charges (item #20) - very interesting...
