This is how they spend their "days off". Dick Winters and Easy Company (Band of Brothers) were spotted at Hitler's residence, the Eagle's Nest

The Easy Company is the 2nd Battalion of the United States Army 506th Parachute Infantry Regiment of the 101st Airborne Division. Popularly known as well as the "Screaming Eagles", it is among the best companies of the U.S. Army. The original band of brother consist of 140 men and 49 of these heroes were killed in action.

Yeah, in case you're wondering -- the mini-series got its concept from Easy Company, which is also known during their hey days as well, the "band of brothers". The fame and bravery of this battalion likewise inspired a number of books and films, such as the iconic "Saving Private Ryan".

The meeting between Iron Man and the Boxing superstar. Robert Downey Jr. and yes, guess who that is!

Two very famous superstars in their younger years indeed. This photo of RDJ and Mike Tyson was taken way back 1986. It's said that this was taken on the same day the two first met -- in Columbus Cafe, New York City. The two eventually became very good friends.

Obviously, RDJ has starred in several iconic films including Chaplin, Zodiac, Sherlock Holmes, Back to School, Home for the Holidays, and of course, the Iron Man and Avengers saga, to name a few. MIke Tyson likewise has a couple of movie stints too. He's starred in Rocky Balboa, The Cookout 2, Champs, I Am Ali, Ip Man 3, among many others.

Anyone remember that movie "Black and White"? It's a 1999 movie which starred RDJ and of course, Mike Tyson was in it. There was this improv scene where he actually slapped and choked RDJ! But of course, it was nothing personal, just work.

Nuclear warfare -- a work in progress. Yes, this wasn't an actual run yet. It's just part of Operation Crossroads in Bikini Atoll in the Pacific.

The Baker Test (as shown in this photo) was done on July 25, 1946. The weapon was placed and detonated underwater, which was the opposite of the approach taken for the Able test. The effect? Radioactive contamination of all target ships.

Japan's formal surrender signed by Douglas MacArthur. This is one of the iconic moments, not only of 1945, but in history.

The surrender of then "Imperial Japan" marked the end of World War II. The surrender was publicly announced August 15, 1945 and was formally signed on September 2nd of the same year aboard the USS Missouri in Tokyo Bay, Japan.

During the summer of 1945, the Allies were eyeing to launch "Operation Olympic" on November of the same year. This invasion of Japan was supposed to be led by U.S. General Douglas MacArthur and was promised to be the bloodiest seaborne attack in history at the expense of the thousand of lives of it soldiers. But the U.S. found an alternative, this was to drop an atomic bomb instead.

The Hiroshima attack was one of the biggest factors that led to the surrender of Japan. About 80,000 people were killed and over hundreds of thousands were wounded when the U.S. B-29 bomber Enola Gay bombed Hiroshima on August 6. It was after the bombing that Japan's war council decided to surrender.

That's the Ku Klux Klan at the circus. As you know, KKK is the infamous and oldest American "hate" groups.

The Ku Klux Klan, popularly known as "KKK" or "the klan", is perhaps the worst kinds of racists in U.S. history. To put in a nut shell, they use violence and terrorism to fight for their causes. Their causes? Simple, white supremacy, white nationalism, anti-immigration, among many others.

KKK started as a social club in 1866 in Pulaski, Tennessee. The first ever leader or "grand wizard", was Nathan Bedford Forrest. The grand wizard ruled over a hierarchy of what they called "grand dragons", "grand titans", and "grand cyclopses".

To most of America back in the days, KKK was more of a cult and circus. Why? Well, members often wore masks and are dressed in the organization's signature long white hooded robes. They likewise made their attacks and other movements at night. But mind you, they did have over 4 million members in the 1920s! Now that's scary, huh?
