Factual error: The film depicts the bombing of Hiroshima, and Colonel Paul Tibbets, commander of the Enola Gay, radioing Washington, DC, requesting permission to drop the bomb. This is inaccurate. To avoid detection, the atomic bomb missions maintained strict radio silence. Colonel Tibbets had permission to drop the weapon from the moment they took off. Not to mention the fact that a radio transmission would never reach the other side of the planet.
Factual error: Eve Curie is shown as having been born before the Curies are nominated for the Nobel Prize in physics, which they eventually won in 1903. However, Even Curie wasn't born until December 6th, 1904.
Factual error: Three B-29 bombers took part in the Hiroshima mission, flying together at 31,000 feet. Enola Gay carried the bomb, Greate Artiste carried scientific instrumentation, and an unnamed third plane carried photographic equipment. The bomb detonated at 1000 feet above the ground, so it is highly unlikely that anyone could have seen it falling.
Factual error: Marie Curie did set up mobile X-ray units during WWI, but they were not on the battlefield, but in field hospitals, well behind the front lines. (No one wants a field hospital to be hit by rifle or artillery fire).
