Days after the German invasion of Poland, Julian Bryan films German planes from the roof of the American Embassy in Warsaw. In his book Siege, Bryan wrote:
Toward the end of the siege I was on the roof of the embassy.... It was so exciting and thrilling that I quite forgot my fear. During the next half-hour I took three hundred feet of film as Nazi planes dove down within a few hundred yards of the embassy roof, seeming, through my view finder, to be almost upon me.
