The Day After Roswell

by Philip Corso

What if the technology that changed the modern world didn’t come from human innovation—but from a crashed UFO? In The Day After Roswell, Colonel Philip J. Corso, a former high-ranking U.S. Army officer, makes one of the most explosive claims in military history—that the U.S. government secretly recovered advanced extraterrestrial technology from the 1947 Roswell crash and reverse-engineered it into modern devices. Did fiber optics, integrated circuits, and night vision all originate from classified UFO research? How did the military bury this knowledge under Cold War-era black projects? What was the connection between Roswell, aerospace advancements, and secret weapons development? A rare firsthand account from inside the U.S. military, this book exposes the classified chain of events that shaped the 20th century’s technological revolution. If true, this would mean that humanity’s greatest innovations were not discovered—but recovered.
