Why was francis Scott key able to see the flag so clear?

Francis Scott Key was able to see the flag clearly because he was positioned at a vantage point during the bombardment of Fort McHenry in 1814, where the flag was prominently displayed atop the fort. The morning light illuminated the flag, allowing him to recognize it despite the chaos of the battle. This sight inspired him to write "The Star-Spangled Banner," which later became the national anthem of the United States.
