Doodle Bugs

My favorite Bible teacher is Dr. Applebee from London.  When he was a young man, he lived in London during WWII.  There were flying bombs, Doodle Bugs, the GI's called them.  They were Ram Jet flying bombs.  (You can see videos about them on YouTube.). When the jet engine ran out of fuel, they just dropped like a stone onto London.  All wondered how they were guided from the low lands.
