USA: Former President Herbert Hoover delivers a radio address saying, "We are not prepared for war" and, "We can help England better by staying out." However, he goes on to warn the Axis powers, "The potential might of this nation is the strongest thing in the whole world" and that "America cannot be defeated."
Former US President Herbert Hoover
Hoover laid it on the line in his radio address by saying that if "we are compelled to act with our military power, let us be thoroughly prepared. Let us make our determination within the frame of our Constitution by the decision of Congress. And when that decision is made there will be no disunity in America. Perhaps the Germans will derive some momentary satisfaction from our unpreparedness, but not for long. The potential might of this nation is the strongest thing in the whole world. If necessary, we can raise and we can eventually equip an army of as many millions of men as we need. We can make more ingenious tools of war and we can operate them better than any nation in the world. That strength is always here in America. The defense of America is not dependent upon any other nation, for America cannot be defeated."

A single-seat monoplane fighter used by the Luftwaffe before and during WWII, the Bf 109 was used as a fighter, interceptor, high-altitude interceptor, fighter-bomber and reconnaissance aircraft
The "F" series, the "Friedrich," saw a complete redesign of the wings, the cooling system and fuselage aerodynamics, and is considered by many as the high-water mark of Bf-109 development.

Charles W Arnett
The 492nd Bomb Group has a special place in the hearts of brothers Paul and David Arnett, the two guys behind this ScanningWWII website. Their father, Charles Arnett, served in the 492nd BG as the pilot of a B-24 Liberator. He was shot down on his third mission and spent a year as a POW at Stalag Luft III where the "Great Escape" took place. It is because of our love for him that we developed a passion for WWII.
