1942 UFO over Los Angeles

In the 1945 Battle of Los Angeles a giant aerial object of unknown origin appears in the night sky!

Los Angeles, February 25, 1942, 02:25 PM-Alarm sirens installed in the event of a Japanese air raid are started as flying objects are seen and announced in the sky. A blackout is declared and the anxious and even terrified inhabitants follow the instructions by turning all the lights off. 03:16 PM Anti-aircraft guns open fire on the unidentified flying objects coming from the ocean, and projector beams are searching the sky. Witnesses observe small objects flying at high altitude, of red or silver plated color, moving in formation at high speed, and untouched by the AAA salvos. This large object was unhurt by many AAA projectiles, according to the reports. Usually known as photograph from the "Battle of Los Angeles."

 The photo, of course, is black and white, so we can’t see the color from it.
Regardless of what it looked like, the military did fire upon the object. Hundreds of rounds hit the object, but it remained undamaged as far as everyone could tell on the ground. However, six people on the ground weren’t as fortunate as the object. They were killed by shell fragments during this battle, which took place amid businesses and residences.
There was no Internet back then to spread the news.

 At 3:06 AM, for reasons unclear, at least four Santa Monica area anti-aircraft batteries turn inland and start firing out over the city and Baldwin Hills, and suddenly "the air over Los Angeles erupted like a volcano." For the next three hours it was nothing but confusion with "swarms" of planes of all possible sizes reported, numbering from one to several hundred, traveling at altitudes from a few thousand feet to more than 20,000, and flying at speeds from very slow to hundreds of miles per hour.
However, whatever it was or whatever they were, no bombs were dropped nor was there any resultant destruction by the invader. So too, despite the fact that 1,440 rounds of anti-aircraft ammunition had been expended, whatever was "up there" seemed impervious to the barrage --- in the end, escaping with no sign of damage or losses.
