How immense must the destruction of hiroshima been for the enola gray crew to have been able to see it?

The destruction of Hiroshima was catastrophic, with an estimated 70,000 to 80,000 people killed instantly and many more suffering from injuries and radiation exposure. The explosion generated a fireball that reached temperatures of several million degrees Celsius, creating a massive mushroom cloud visible from miles away. The Enola Gay crew, flying at an altitude of approximately 30,000 feet, witnessed this devastating spectacle as a stark reminder of the bomb's unprecedented destructive power. The sight must have been both awe-inspiring and profoundly unsettling for the crew.
