Video - Secrets and Surprises of WWII

Did you know that during World War II, British spies used a crazy technique to send secret messages? They would hide microdots, tiny photographs the size of a period, in the postage stamps on letters. And get this: the Nazis had a secret weapon called the Fritz X, an early version of a guided bomb! Also, in 1941, a British soldier survived a fall of over 18,000 feet without a parachute and only suffered a sprained leg. Talk about a lucky landing! Speaking of bizarre, did you know that the Russians trained dogs to carry explosives and blow up enemy tanks? War is strange, isn't it? Share your thoughts in the comments!
